摘　　要：以SBA-15为载体,采用双溶剂法制备了不同负载量的纳米银催化剂,考察了催化剂样品催化CO选择性氧化性能,以X射线衍射、透射电子显微镜、电感耦合等离子体发射光谱等手段表征了催化剂的结构.结果表明:负载量为5.76%的Ag/SBA-15催化剂在CO选择性氧化反应中表现出优异的催化性能.Nano-Ag catalyst samples with different capacities were prepared by a double solvent technique with SBA-15 as support.The catalytic activity for preferential oxidation of carbon monoxide were studied.The catalyst samples were characterized by X-ray diffraction,transmission electron microscopy and inductively coupled plasma-atomic emission spectroscopy.The results showed that the capacity up to 5.76% of the Ag/SBA-15 catalyst exhibited excellent catalytic performance in CO selective oxidation reaction.
