1Highly active and sintering-resistant heteroepitaxy of Au nanoparticles on ZnO nanowires for CO oxidation显示文摘Gold was supported on commercial ZnO powders(P) and homemade ZnO nanowires(NWs) by a modified deposition–precipitation method. X-ray diffraction and transmission electron microscopy investigation indicated that the size of the Au nanoparticles(NPs) depended strongly on the calcination temperature.The Au NPs were highly dispersed(< 5 nm) on both supports with calcination temperatures < 400 °C.However, after calcination at 600 °C the Au NPs aggregated much more severely on ZnO P than on ZnO NWs. Gold NPs epitaxially grew into the {10–10} facets of the ZnO NWs after calcination at temperatures > 400 °C. Such unique anchoring mechanism accounts for the much better experimentally observed sintering resistance. X-ray photoelectron spectra showed that Au existed as both metallic Au0 and Auδ+species in all the synthesized catalysts with or without calcination treatment; the ratios of Auδ+/Au0,however, varied, depending on the treatment conditions. Catalytic tests showed that the activity for CO oxidation strongly depended on the size of the Au NPs. After calcination at 600 °C, the specific rate for CO oxidation at room temperature decreased about 30 times on Au/ZnO P but only about 4 times on Au/ZnO NW. Stability tests demonstrated that the Au/ZnO NW catalysts had better stability for CO oxidation.Jiaxin Liu Botao Qiao Yian Song Hailian Tang Yudong Huang Jingyue(Jimmy) Liu 2016Journal of Energy Chemistry2016,25,3:2

6ZnO纳米线负载Pd_1单原子催化剂催化若干反应性能的考察(英文)显示文摘将孤立的Pd原子分散到ZnO纳米线(NWs)上作为单原子催化剂(SACs),并考察了它们在若干反应中的催化性能.Pd_1/Zn O SAC对甲醇蒸汽重整制氢反应表现出高的活性、稳定性和CO_2选择性.该催化剂体系对CO和H_2的氧化也具有高活性,但在富氢物料中CO优先氧化反应中的催化剂性能较差,这主要是由于在Zn O负载的Pd_1原子上H_2氧化的强竞争反应所致.常压下在Pd_1/ZnO SAC上就可发生逆水汽变换反应.该系列催化反应测试结果清楚地表明,选择合适金属与载体对开发分子催化转化用单原子催化剂至关重要.Jia Xu Yian Song Honglu Wu Jingyue Liu 2017Chinese Journal of Catalysis2017,38,9:0
