| 1 | 超声浸渍法制备Pd/Al_2O_3催化剂及其催化蒽醌加氢性能显示文摘以球形-γAl2O3和-θAl2O3为载体,分别采用超声浸渍和普通浸渍方法制备了Pd含量为0.3%的负载型催化剂,并将其用于蒽醌加氢反应.采用X射线衍射、N2吸附和透射电镜等手段对催化剂的理化性质和孔结构进行了分析,考察了浸渍方法对催化剂活性金属分散度的影响.结果表明,与普通浸渍法相比,超声浸渍法制备的负载型Pd催化剂金属分散度明显提高,因而对蒽醌加氢反应表现出较高的催化活性.以960℃焙烧的球形-θAl2O3为载体,通过超声浸渍制备的负载型Pd催化剂具有较高的Pd分散度和较大的孔径,在蒽醌加氢反应中对反应物的扩散阻力较小,因而表现出更高的催化活性,而且反应中催化剂的稳定性良好. | 杨永辉 林彦军 冯俊婷 David G.Evans 李殿卿 | 2006 | 催化学报2006，27，4： | 29 |
| 2 | γ-Al_2O_3表面原位合成Ni-Al-CO_3 LDHs研究显示文摘Ni-Al-CO3 LDHs/γ-Al2O3 have been prepared using an in-situ synthesis technique. NH3·H2O was chosen as activation agent of Al on the γ-Al2O3 surface as well as precipitant. Ni-Al-CO3 LDHs/γ-Al2O3 was synthesized by controlling the reaction conditions such as temperature, concentration of Ni2+ and initial pH. The crystalline structure, chemical composition and porous structure were characterized by means of XRD, FT-IR, TG-DTA, 27Al MAS-NMR and N2 adsorption-desorption. The resulting sample of Ni-Al-CO3 LDHs/γ-Al2O3 possesses higher specific area and narrower pore distribution, in which Ni-Al-CO3 LDHs are located on the surface of γ-Al2O3 and share the same Al-O bonds with the γ-Al2O3 lattice. Finally a possible structural model was proposed to account for the porous characters of Ni-Al-CO3 LDHs/γ-Al2O3. | 毛纾冰 李殿卿 张法智 David G.Evans 段雪 | 2004 | 无机化学学报2004，20，5： | 15 |
| 3 | 柠檬酸溶胶凝胶法制备LiCoO_2电极材料及其表征显示文摘LiCoO2 precursors of the cathode material for lithium ion batteries were prepared from lithium hydroxide, basic cobalt carbonate and citric acid by a sol gel method. The LiCoO2 samples were obtained by sintering the gel precursors at different temperatures and for different times. The thermal decomposition behavior of the gel precursors was examined by means of thermo gravimetric analysis and differential thermal analysis using a PCT IA thermal analyzer system. Their structures and morphologies were characterized by powder XRD and SEM techniques. It was found that using citric acid realized that the formation of LiCoO2 crystal can be clearly differentiated to the nucleation and growth processes of the crystals; furthermore, the crystal size can be controlled. Electrochemical tests using the LAND BT1 10 test system showed the electrochemical performance of the material is affected by its integrity and stability. | 王兴杰 杨文胜 卫敏 David G.Evans 段雪 | 2003 | 无机化学学报2003，19，6： | 13 |

| 11 | Preparation and photochromic properties of NiAl-NO_3-LDHs/LDPE composite显示文摘Nanoscale NiAl-NO3-LDHs with good crystallinity have been synthesized by a method, Separate Nucleation and Aging Steps (SNAS). An NiAl-NO3-LDHs/LDPE composite was prepared by blending NiAl-NO3-LDHs and LDPE in a heated double-roller mixer. The color of this composite changed from olive green to steel gray under UV irradiation. After heating at 80oC for 2 h, the color returned to olive green. The effect of varying the amount of added NiAl-NO3-LDHs and UV exposure time on the photochromic properties of the composite has been investigated. The results showed that the photochromic phenomenon becomes more apparent with increasing amount of NiAl-NO3-LDHs. When the amount reaches 5%, the composite exhibits good photochromic properties and reproducibility. The color change rate of the composite reaches a maximum when the irradiation time exceeds 20 min. The addition of LDPE improves the photochromic cyclability of NiAl-NO3-LDHs significantly. The addition of nanoscale NiAl-NO3-LDHs also improves the mechanical properties of LDPE to some extent. | CHO Kyuhaeng David G.EVANS | 2007 | Chinese Science Bulletin2007，52，7： | 1 |

| 18 | Searching for a route to synthesize in situ epitaxial Pr_(2)Ir_(2)O_(7) thin films with thermodynamic methods显示文摘In situ growth of pyrochlore iridate thin films has been a long-standing challenge due to the low reactivity of Ir at low temperatures and the vaporization of volatile gas species such as IrO_(3)(g)and IrO_(2)(g)at high temperatures and high PO_(2).To address this challenge,we combine thermodynamic analysis of the Pr-Ir-O_(2)system with experimental results from the conventional physical vapor deposition(PVD)technique of co-sputtering.Our results indicate that only high growth temperatures yield films with crystallinity sufficient for utilizing and tailoring the desired topological electronic properties and the in situ synthesis of Pr_(2)Ir_(2)O_(7)thin films is fettered by the inability to grow with PO_(2)on the order of 10 Torr at high temperatures,a limitation inherent to the PVD process.Thus,we suggest techniques capable of supplying high partial pressure of key species during deposition,in particular chemical vapor deposition(CVD),as a route to synthesis of Pr_(2)Ir_(2)O_(7). | Lu Guo Shun-Li Shang Neil Campbell Paul G.Evans Mark Rzchowski Zi-Kui Liu Chang-Beom Eom | 2021 | npj Computational Materials2021，，1： | 0 |
