【摘要】 <正>二氧化铈是一种重要的稀土氧化物功能材料,在催化(汽车尾气处理)、固体氧化物燃料电池、机械抛光、气敏器件等领域有着非常广泛的应用[1]。作为一种催化剂,二氧化铈的催化性能受其尺寸、形貌的影响[2]。所以为获得具有良好催化能力的二氧化铈材料,对其尺寸及形貌的进行合理的节非常重要。在我们组前更多还原

【Abstract】 Ceria is one of the most important rare earth functional materials, it is widely used in the catalysis(the treatment of automobile exhaust gases), SOFC, mechanical polishing materials, gas sensors and so forth. The size and morphology are quite important for the catalytic capacity of ceria. In our previous study, we have successfully synthesized ceria nanoflowers with high CO oxidation catalytic capacity. Herein, by using the injection method and carefully choosing the morphology controlled reagents, we synthesized ultrathin ceria nanoplate with the thickness of 1.2 nm and tested their catalytic capacity.更多还原
