| 5 | Integration of two-dimensional morphology and porous surfaces to boost methanol electrooxidation performances of PtAg alloy nanomaterials显示文摘As an attempt to minimize the usage amounts of noble metals in catalysis,PtAg alloy nanocrystals with a porous nanosheet morphology were fabricated through a galvanic replacement reaction.During the reaction,ascorbic acid was added to the solution to protect the Ag triangular nanoplates from being totally etched. Structural characterizations indicated that the obtained nanocrystals had thin porous basal planes and winding edges with abundant bulges.Such unique two-dimensional porous architectures endowed this nanomaterial with plenty of catalytically active sites and structural benefits in electron and mass moving, as well as morphology stability.Electrochemical tests proved that the PtAg porous nanosheets had superior catalytic activity and durability towards methanol electrooxidation in basic media.Specifically,the mass and specificactivities of the PtAg porous nanosheets were 4.5and 2.7times higher than those of a commercial Pt/C catalyst.In addition to the special structures,the introduction of Ag enhanced the catalytic performances of the PtAg porous nanosheets. | Changshuai Shang Yaxiao Guo Erkang Wang | 2018 | Nano Research2018，11，12： | 2 |
| 6 | 原位表面掺杂增强PtNiCoRh纳米晶对C_(1)燃料电氧化的催化性能显示文摘异质原子掺杂的铂基纳米晶在多相催化领域具有广阔的应用前景,然而基于原位表面掺杂策略来优化表面原子构型仍颇具挑战.本研究通过原位表面掺杂的化学方法制备出多枝状PtNiCoRh四元金属纳米晶.抗坏血酸和铑离子的配位作用实现了铑离子的延迟还原,从而可控地将铑原子锚定在催化剂表面层.电催化研究表明原位表面掺杂的Pt_(67)Ni_(16)Co_(16)Rh_(1)纳米晶针对甲醇、甲醛和甲酸电氧化都具有优异的催化活性、稳定性及抗CO中毒特性.原位电化学红外光谱结果表明抗腐蚀性强的铑原子的表面掺杂能有效调控催化剂表面Pt位点,其中CO中毒中间体以更容易氧化消除的桥位态吸附在Rh–Pt异质位点.本研究提出的原位表面掺杂策略将有助于设计高原子利用率的高效多相催化剂. | 王伟 陈雪皎 叶进裕 张玉辉 韩艳晨 陈孝为 刘凯 谢水奋 | 2021 | Science China Materials2021，64，5： | 1 |
| 7 | 煤基液体燃料加氢脱氮催化剂的研究动态显示文摘煤基粗油中氮含量高达4500mg/L左右,采用石油系的NiMoS催化剂很难实现含氮芳香族化合物的脱除。为开发针对性更强、更高效的加氢脱氮催化剂,本文对煤基粗油加氢脱氮的催化剂研究动态进行了综述。首先介绍了煤基粗油中含氮芳香族化合物的组成及特点,接着围绕传统硫化物催化剂和脱氮性能较高的贵金属催化剂,从活性相的构筑与调控、载体在催化剂中的作用等方面进行了分析,最后比较了上述两种催化剂的催化性能。结果表明:贵金属催化剂活性高于传统硫化物催化剂;添加助金属形成合金可提高贵金属耐硫性与稳定性;采用具有一定酸性、与活性中心相互作用适中的载体的催化剂脱氮性能更佳。在综合分析已有文献和工作基础上,得出只有依据反应体系、特定反应过程来设计专一的加氢脱氮催化剂,才能从根本上提高含氮化合物的脱除率。 | 薛怡凡 宋云彩 冯杰 李文英 | 2021 | 化工进展2021，40，S02： | 0 |
| 8 | The size effect and high activity of nanosized platinum supported catalysts for low temperature oxidation of volatile organic compounds显示文摘Pt/Al_(2)O_(3) catalysts with smaller size of Pt nanoparticles were prepared by ethylene glycol reduction method in two different way and their oxidation activities for three typical VOCs(volatile organic compounds)were evaluated.The catalyst prepared by first adsorption and then reduction procedure is denoted as L-Pt/Al_(2)O_(3) while the catalyst prepared by first reduction and then loading procedure is defined as R-Pt/Al_(2)O_(3).The results show that L-Pt/Al_(2)O_(3) with the stronger interaction between Pt species and Al_(2)O_(3) exhibit smaller size of Pt nanoparticles and favorable thermal stability compared with R-Pt/Al_(2)O_(3).L-Pt/Al_(2)O_(3) is favor of the formation of more adsorbed oxygen species and more Pt^(2+)species,resulting in high catalytic activity for benzene and ethyl acetate oxidation.However,R-Pt/Al_(2)O_(3) catalysts with higher proportion of Pt^(0)/Pt^(2+)and bigger size of Pt particles exhibits higher catalytic activity for n-hexane oxidation.Pt particles in R-Pt/Al_(2)O_(3) were aggregated much more serious than that in L-Pt/Al_(2)O_(3) at the same calcination temperature.The Pt particles supported on Al_(2)O_(3) with~10 nm show the best catalytic activity for n-hexane oxidation. | Ziqing Yuan Ziyu Chen Jianxin Mao Renxian Zhou | 2021 | Chinese Journal of Chemical Engineering2021，34，11： | 0 |
| 9 | Bridging oxidase catalysis and oxygen reduction electrocatalysis by model single-atom catalysts显示文摘Nanocatalysts with enzyme-like catalytic activities,such as oxidase mimics,are extensively used in biomedicine and environmental treatment.Searching for enzyme-like nanomaterials,clarifying the origins of catalytic activity and developing activity assessment methodologies are therefore of great significance.Here,we report that oxidase catalysis and oxygen reduction reaction(ORR)electrocatalysis can be well bridged based on their identical activity origins,which makes facile electrocatalytic ORR activity measurements intrinsically applicable to oxidase-like activity evaluations.Inspired by natural heme-copper oxidases,Cu/Fe-doped single-atom catalysts(SACs)were first synthesized and used as model catalysts.Chromogenic reactions,electrochemical voltammetric measurements and density functional theory calculations further verified the linear relationship between the oxidase-like and ORR catalytic activities of the catalysts;thus,an effective descriptor(|jn|)is proposed for rapid enzymatic catalyst evaluation.Evidence suggests that the enhanced tumour therapeutic efficacy of SACs is a result of their oxidase-like/ORR activities,which proves that numerous ORR electrocatalysts are promising candidates for oxidase mimics and tumour therapy.The synergistic catalytic effect of the biomimetic heterobinuclear Cu-Fe centres has also been thoroughly probed. | 逯向雨 高珊珊 林翰 田汉 徐德良 施剑林 | 2022 | National Science Review2022，9，10： | 0 |
