英文摘要	Mesoporous multimetal oxide microspheres (Ni-Ce-Al-O) with tuned and uniformly distributed composition are prepared through an aerosol-assisted self-assembly approach and further used as catalysts for ammonia decomposition. The as-prepared and spent materials are characterized by various techniques including ex situ/in situ X-ray diffraction (XRD), X-ray absorption fine structure (XAFS), scanning electron microscope (SEM)/transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and N-2-adsorption. The tricomponent Ni-Ce-Al-catalysts show great superiority over pure NiO or bicomponent catalysts (Ni-Ce-O and Ni-Al-O) in both catalytic activity and durability. By using H-2-TPR combined with in situ XRD, we have identified metallic Ni-0 as the active crystalline phase and further confirmed the strong interaction between alumina and other components. This strong interaction helps suppress the growth of both metallic Ni-0 as active site and ceria as promoter under the harsh catalytic conditions (high temperature and reducing atmosphere) and thus improves the activity and stability simultaneously.; National Science Foundation of China (NSFC) [21301107, 21373259, 21331001]; Fundamental research funding of Shandong University [2014JC005]; Taishan Scholar project of Shandong Province (China); Open Funding from State Key Laboratory of Material Processing and Die & Mold Technology at Huazhong University of Science and Technology [P2014-10]; Hundred Talents project of the Chinese Academy of Sciences; Strategic Priority Research Program of the Chinese Academy of Sciences [XDA09030102]; U.S. Department of Energy [DE-AC02-06CH11357]; Canadian Light Source; SCI(E); EI; ARTICLE; jinzhao@sdu.edu.cn; sirui@sinap.ac.cn; jiacj@sdu.edu.cn; 14; 7685-7696; 120
