采用溶胶 凝胶法制备了Ce1-XCuXOY固溶体催化剂,通过XRD,BET,TEM等表征研究了该类催化剂的结构特征,并采用H2 TPR技术考察了其氧化还原行为.结果表明固溶体的生成使该类催化剂活化和转移氧的能力大大提高.该类催化剂在甲醇自热制氢反应中表现了较高的催化活性.
The solid-state catalysts Ce1-XCuXOY were prepared by sol-gel method and their structures were characterized by XRD, BET and TEM. The redox behavior of the catalysts was investigated by H2 TPR. The results show that the solid solution The ability of the catalyst to activate and transfer oxygen is greatly enhanced. Such catalysts show high catalytic activity in the methanol autothermal hydrogen production.
