| 4 | Catalytic performance of Fe_3O_4-CoO/Al_2O_3 catalyst in ozonation of 2-(2,4-dichlorophenoxy) propionic acid,nitrobenzene and oxalic acid in water显示文摘Fe3O4-CoO/Al2O3 catalyst was prepared by incipient wetness impregnation using Fe(NO3) 3·9H2O and Co(NO3) 2·6H2O as the precursors,and its catalytic performance was investigated in ozonation of 2-(2,4-dichlorophenoxy) propionic acid(2,4-DP) ,nitrobenzene and oxalic acid.The experimental results indicated that Fe3O4-CoO/Al2O3 catalyst enabled an interesting improvement of ozonation eciency during the degradation of each organic pollutant,and the Fe3O4-CoO/Al2O3 catalytic ozonation system followed a radical-type mechanism.The kinetics of ozonation alone and Fe3O4-CoO/Al2O3 catalytic ozonation of three organic pollutants in aqueous solution were discussed under the mere consideration of direct ozone reaction and OH radical reaction to well investigate its performance.In the catalytic ozonation of 2,4-DP,the apparent reaction rate constants(k) were determined to be 1.456×10-2 min-1 for ozonation alone and 4.740×10-2 min-1 for O3/Fe3O4-CoO/Al2O3.And O3/Fe3O4-CoO/Al2O3 had a larger Rct(6.614×10-9) calculated by the relative method than O3 did(1.800×10-9) ,showing O3/Fe3O4-CoO/Al2O3 generated more hydroxyl radical.Similar results were also obtained in the catalytic ozonation of nitrobenzene and oxalic acid.The above results demonstrated that the catalytic performance of Fe3O4-CoO/Al2O3 in ozonation of studied organic substance was universal to a certain degree. | Shaoping Tong,Rui Shi,Hua Zhang,Chunan Ma College of Chemical Engineering and Materials Science,State Key Laboratory Breeding Base of Green Chemistry-Synthesis Technology,Zhejiang University of Technology,Hangzhou 310032,China | 2010 | Journal of Environmental Sciences2010,22,10: | 10 |
| 5 | Periodicity and map for discovery of new ionic liquids显示文摘There is virtually no limit in the number of ionic liquids. How to select proper ones or discover new ones with desirable properties in such a large pool of ionic liquids? It has become a bottleneck in the researches and applications of ionic liquids. Mendeleev’s periodic law states that the properties of the elements vary periodically. Whether the similar regularity exists among ionic or mo-lecular fragments of compounds is an interesting topic. In this work, we attempted to establish a pe-riodicity and draw a “map” of ionic liquids for providing definite guidance to discover, design, and se-lect the proper ionic liquids rather than trial-and-error. If a complete regularity of the system of ionic liquids can be finally established in the future, we are near an epoch in understanding the existing differences and the reasons for the similarity of the ions or molecular fragments. | ZHANG Suojiang, SUN Ning, ZHANG Xiangping & Lü Xingmei Research Laboratory for Green Chemical Engineering and Technology, Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100080, China Correspondence should be addressed to Zhang Suojiang | 2006 | Science China Chemistry2006,49,2: | 9 |
| 6 | Cellulose conversion to polyols on supported Ru catalysts in aqueous basic solution显示文摘It is of great significance and challenge to achieve direct conversion of cellulose to specific polyols,e.g.,ethylene glycol and propylene glycol.For such selective conversion,a novel one-pot approach was studied by combination of alkaline hydrolysis and hydrogenation on supported Ru catalysts.A wide range of bases including solid bases,e.g.,Ca(OH)2 and La2O3,and phosphate buffers were examined in the cellulose reaction in water,and the cellulose conversions and polyol products depended largely on the basicity or pH values in the aqueous solutions.Ethylene glycol,1,2-propanediol,and especially 1,2,5-pentanetriol were obtained with selectivities of 15%,14% and 22%,respectively,at 38% cellulose conversion at pH 8 in phosphate buffer solution.These preliminary results provide potentials for efficient conversion of cellulose to targeted polyols by using the advantages of bases. | DENG TianYin,SUN JiYing & LIU HaiChao Beijing National Laboratory for Molecular Sciences,State Key Laboratory for Structural Chemistry of Stable and Unstable Species Green Chemistry Center,College of Chemistry and Molecular Engineering,Peking University,Beijing 100871,China | 2010 | Science China Chemistry2010,53,7: | 8 |
| 7 | Clean synthesis of biodiesel over solid acid catalysts of sulfonated mesopolymers显示文摘FDU-15-SO3H,a solid acid material prepared from the sulfonation of FDU-15 mesoporous polymer,has been demonstrated to serve as an efficient catalyst in the esterification of palmitic acid with methanol as well as in the transesterification of fatty acid-edible oil mixture.FDU-15-SO3H achieved an acid conversion of 99.0% when the esterification was carried out at 343 K with a methanol/palmitic acid molar ratio of 6:1 and 5 wt% catalyst loading.It was capable of giving 99.0% yield of fatty acid methyl esters (FAME) when the transesterification of soybean oil was performed at 413 K and the methanol/oil weight ratio of 1:1.FDU-15-SO3H was further applied to the transesterification/esterification of the oil mixtures with a varying ratio of soybean oil to palmitic acid,which simulated the feedstock with a high content of free fatty acids.The yield of FAME reached 95% for the oil mixtures containing 30 wt% palmitic acid.This indicated the sulfonated mesopolymer was a potential catalyst for clean synthesis of fuel alternative of biodiesel from the waste oil without further purification. | FANG Lin,XING Rong,WU HaiHong,LI XiaoHong,LIU YueMing & WU Peng Shanghai Key Laboratory of Green Chemistry and Chemical Processes Department of Chemistry,East China Normal University,Shanghai 200062,China | 2010 | Science China Chemistry2010,53,7: | 7 |
| 8 | Modification of LiCo_(1/3)Ni_(1/3)Mn_(1/3)O_2 cathode material by CeO_2-coating显示文摘LiCo1/3Ni1/3Mn1/3O2 was coated by a layer of 1.0 wt% CeO2 via sol-gel method. The bared and coated LiMn1/3Co1/3Ni1/3O2 was characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM),cyclic voltammogram (CV) and galvanotactic charge-discharge test. The results show that the coating layer has no effect on the crystal structure,only coating on the surface; the 1.0 wt% CeO2-coated LiCo1/3Ni1/3Mn1/3O2 exhibits better discharge capacity and cycling performance than the bared LiCo1/3Ni1/3Mn1/3O2. The discharge capacity of 1.0 wt% CeO2-coated cathode is 182.5 mAh.g-1 at a current density of 20 mA.g-1,in contrast to 165.8 mAh.g-1of the bared sample. The discharge capacity retention of 1.0 wt% CeO2-coated sample after 12 cycles reaches 93.2%,in comparison with 86.6% of the bared sample. CV results show that the CeO2 coating could suppress phase transitions and prevent the surface of cathode material from direct contact with the electrolyte,thus enhance the electro-chemical performance of the coated material. | WANG Meng,WU Feng,SU YueFeng & CHEN Shi Beijing Key Laboratory of Environment,School of Chemical Engineering and Environment,Beijing Institute of Technology National Development Center of High Technology Green Materials,Beijing 100081,China | 2009 | Science China(Technological Sciences)2009,52,9: | 7 |
| 9 | A new perylene diimide-based colorimetric and fluorescent sensor for selective detection of Cu^(2+) cation显示文摘A new perylene diimide (PDI) ligand (1) functionalized with a dipicolylethylenediamine (DPEN) moiety was synthesized and first used as a colorimetric and fluorometric dual-channel sensor to specifically detect the presence of Cu2+ over a wide range of other cations. The solution of 1 (10 μmol/L) upon ad-dition of Cu2+ displayed distinguishing pink color compared with other cations including K+,Ni2+,Ca2+,Mn2+,Na+,Sr2+,Zn2+,Co2+,Cd2+,Mg2+,Cr3+,Ag+,and Ba2+,indicating the sensitivity and selectivity of 1 to Cu2+. Thus,the advantage of this assay is that naked-eye detection of Cu2+ becomes possible. More-over,among these metal ions investigated,only Cu2+ quenched more than half fluorescent intensity of 1. The ESI-TOF spectrum of a mixture of 1 and CuCl2 in combination of the fluorescence titration spectra of 1 (10 μmol/L) upon addition of various amounts of Cu2+ revealed the formation of a 2︰1 metal-ligand complex through the metal coordination interaction. | YAN LiWei,YANG Li,LAN JingBo & YOU JingSong Key Laboratory of Green Chemistry and Technology of Ministry of Education,College of Chemistry,and State Key Laboratory of Biotherapy,West China Hospital,West China Medical School,Sichuan University,Chengdu 610064,China | 2009 | Science China Chemistry2009,52,4: | 6 |
| 10 | Water gas shift activity of Co-Mo/MgO-Al_2O_3 catalysts presulfided with ammonium sulfide显示文摘Co-Mo/MgO-Al2O3 catalyst was presulfided with ammonium sulfide in aqueous solution and activated with synthesis gas for water gas shift reaction. The assay results indicate that the presulfided Co-Mo/MgO-Al2O3 catalyst exhibits an excellent catalytic activity and stability. XRD and EPR characterization results show that the O-S exchange might occur during the impregnation, leading to the formation of (NH4)2MoS4 (or (NH4)2MoxSy) precursor, which was then thermally decomposed and reduced to MoS2. The higher catalytic performance is attributed to an optimization formation of active Co-Mo sulfides, consisting of well dispersed MoS2 and Co-Mo-S phase due to the redispersion of Co sulfide particles over the edges of newly formed MoS2 crystallites. | Yixin Lian, Huifang Wang, Weiping Fang, Yiquan Yang Department of Chemistry, College of Chemistry and Chemical Engineering, National Engineering Laboratory for Green Chemical Productions of Alcohols, Ethers and Esters, Xiamen University, Xiamen 361005, Fujian, China | 2010 | Journal of Natural Gas Chemistry2010,19,1: | 4 |
| 11 | A new approach to the synthesis of diacetals(diketals) pentaerythritol catalyzed by SO_3H-functionalized ionic liquids显示文摘In this article,an efficient,simple and environmentally friendly approach to the synthesis of diacetals(diketals) pentaerythritol using SO3H-functionalized ionic liquids(ILs) as catalysts was reported.The ILs show high catalytic activity and reusability with good to excellent yields of the desired products.Hammett method has been used to determine the acidity order of these ionic liquids and the results are consistent with the catalytic activities observed in acetalization reaction.Maximum product yield of 93%was observed on using[PSPy][OTf]as catalyst and it can be reused at least 8 times without obvious activity loss. | Yuan Yuan Wang,Yan Nan Xu,Zhi Zhong Wang,Li Yi Dai Shanghai Key Laboratory of Green Chemistry and Chemical Process,Department of Chemistry, East China Normal University,Shanghai 200062,China | 2010 | Chinese Chemical Letters2010,21,5: | 4 |
| 12 | Catalytic selective oxidation or oxidative functionalization of methane and ethane to organic oxygenates显示文摘Selective oxidation or oxidative functionalization of methane and ethane by both homogeneous and heterogeneous catalysis is presented concerning: (1) selective oxidation of methane and ethane to organic oxygenates by hydrogen peroxide in a water medium in the presence of homogeneous osmium catalysts, (2) selective oxidation of methane to formaldehyde over highly dispersed iron and copper heterogeneous catalysts, (3) selective oxidation of ethane to acetaldehyde and formaldehyde over supported molybdenum catalysts, and (4) oxidative carbonylation of methane to methyl acetate over heterogeneous catalysts containing dual sites of rhodium and iron. | WANG Ye*, AN DongLi & ZHANG QingHong State Key Laboratory of Physical Chemistry of Solid Surfaces, National Engineering Laboratory for Green Chemical Productions of Alcohols, Ethers and Esters, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China | 2010 | Science China Chemistry2010,53,2: | 4 |
| 13 | Efficient expression of codon-adapted human acetaldehyde dehydrogenase 2 cDNA with 6×His tag in Pichia pastoris显示文摘Human mitochondrial acetaldehyde dehydrogenase 2 (ALDH2) catalyzes the oxidation of acetaldehyde to acetic acid. Therefore, ALDH2 has therapeutic potential in detoxification of acetaldehyde. Further-more, ALDH2 catalyzes nitroglycerin to nitrate and 1, 2-glyceryldinitrate during therapy for angina pectoris, myocardial infarction, and heart failure. Large quantities of ALDH2 will be needed for potential clinical practice. In this study, Pichia pastoris was used as a platform for expression of human ALDH2. Based on the ALDH2*1 cDNA sequence, we designed ALDH2 cDNA by choosing the P. pastoris preferred codons and by decreasing the G + C content level. The sequence was synthesized using the overlap extension PCR method. The cDNA and 6×His tags were subcloned into the plasmid pPIC9K. The recombinant protein was expressed in P. pastoris GS115 and purified using Ni2+-Sepharose affinity chromatography. The amount of secreted protein in the culture was 80 mg/L in shake-flask cultivation and 260 mg/L in high-density bioreactor fermentation. Secreted ALDH2 was easily purified from the culture supernatant by using Ni2+-Sepharose affinity chromatography. After purification of the fermentation supernatant, the enzyme had a specific activity of 1.2 U/mg protein. The yield was about 16 mg/L in a shake flask culture of P. pastoris GS115 which contained the original human ALDH2*1 cDNA. | ZHAO YuFeng1,2, LEI MingKe2, WU YuanXin2, ZHANG ZiSheng3 & WANG CunWen2 1 State key Laboratory of Agricultural Microbiology, College of Life Science and Technology, Huazhong Agriculture University, Wuhan 430070, China 2 Key Laboratory for Green Chemical Processes of the Ministry of Education, Hubei Key Lab of Novel Reactor & Green Chemical Technology, School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, Wuhan 430074, China 3 Department of Chemical Engineering, University of Ottawa, Ottawa, Canada K1N 6N5 | 2009 | Science China(Life Sciences)2009,52,10: | 3 |
| 14 | Recognition behavior of chiral nanocomposites toward biomolecules and its application in electrochemical immunoassay显示文摘The novel nanocomposites were obtained by covalently linking arginine enantiomers with the sidewall of multi-walled carbon nanotubes,and utilized as sensing materials for biomolecular recognition in electrochemical immunoassay.They were characterized by X-ray photoelectron spectroscopy (XPS),transmission electron microscopy (TEM) and circular dichroism spectroscopy (CD).Nano-gold and Prussian Blue were employed to amplify the analytical signal responses.Prostate specific antibody/antigen and carcinoembryonic antibody/antigen were used as model systems.The results showed that the different configurations of nanocomposites could readily facilitate chiral recognition of antibodies,and D-nanocomposites displayed a larger signal. | FU YingZi1,CHEN Min1,CUI Xin2,WANG LiLan1,CHEN Qiao1 & ZHOU Juan1 1Key Laboratory on Luminescence and Real-Time Analysis,Ministry of Education College of Chemistry and Chemical Engineering,Southwest University,Chongqing 400715,China 2Key Laboratory of Green Chemistry & Technology,Ministry of Education College of Chemistry,Sichuan University,Chengdu 610064,China | 2010 | Science China Chemistry2010,53,6: | 2 |
| 15 | Size and support effects for CO oxidation on supported Pd catalysts显示文摘Supporting Pd catalysts characterized significant different size distribution were obtained using PdCl2,[Pd(NH3)4](NO3)2 and Pd(acac)2 as precursors.High-resolution transmission electron microscopy(TEM),X-ray diffraction(XRD),in-situ Fourier transform infrared spectroscopy(FTIR) and Raman spectroscopy were used to examine the dispersion of Pd.Catalytic performance measurements show that the activities for CO oxidation increase as the Pd particle size decreases and the O2/CO ratio increases.The activities under oxygen rich conditions are significantly higher than those at near the stoichiometric conditions.Pd on TiO2 prepared by the Pd(acac)2 precursor is highly dispersed,leading to a considerable activity for CO oxidation at near room temperature.CO oxidation on the 1 wt% Pd/TiO2 and under an O2/CO ratio of 1 characterized an apparent activation energy of 36.7 kJ/mol,which is closed to those reported for CO oxidation on the supported Au catalysts.The present work demonstrates a high catalytic activity of highly dispersed noble metals,and suggests a promising approach of using noble metals as catalysts with exceeding high efficiency. | WANG ZhaoWen,LI Bin,CHEN MingShu,WENG WeiZheng & WAN HuiLin State Key Laboratory of Physical Chemistry of Solid Surfaces National Engineering Laboratory for Green Chemical Productions of Alcohols-Ethers-Esters Department of Chemistry,College of Chemistry and Chemical Engineering,Xiamen University,Xiamen 361005,China | 2010 | Science China Chemistry2010,53,9: | 2 |
| 16 | 深源地震:橄榄石→尖晶石相变诱发断层显示文摘70年代以来,人们已经知道在地球几百公里处有深源地震存在,在这个深处压力和温度不可能使岩石产生脆性剪切断裂。在300km之下,地震出现频率随深度增加而迅速减少,但是在600km处又再次增加,在700km处深源地震停止。五年之前,我们发现这种深源地震与一种新的塑性不稳定性有关。在地球400km处,当上地幔最主要矿物橄榄石(Mg,Fe)_2SiO_4发生相变时会导致一种新的断层类型产生。我们首先利用锗橄榄石Mg_2GeO_4,(即晶体结构与镁铁橄榄石相同,而化学成分有所不同,它可以在比较低压力条件下发生相变)进行模拟实验,借以证明在上地幔很高压力条件下橄榄石也会发生相变。这种新的机制叫自组织类的脆性断裂(self─organizinglikebritlefailure),其特征是:在断层生长过程中会释发地震能量;在由很细尖晶石颗粒组成的“超塑性层”中会发生断层滑移(即所谓显微反向断裂,microanticrack)。由这种机制形成的断层只在放热反应过程中产生,它可以用来解释为什么深源地震停止于700km,因为在这个深度,橄榄石到尖晶石相变为下地幔高密度矿物的吸热反应。深源地震的地震学证据与这种新机制是一致的。 | Harry W.
