Influence of transition metals doping on the catalytic performance of CuO-CeO2 catalysts for the preferential oxidation of CO in excess hydrogen(过渡金属修饰对铜铈催化剂在选择性脱除CO反应中催化性能的影响)

Influence of transition metals doping on the catalytic performance of CuO-CeO2 catalysts for the preferential oxidation of CO in excess hydrogen(过渡金属修饰对铜铈催化剂在选择性脱除CO反应中催化性能的影响)

过渡金属（Mn、Fe、Ni、Zn、Co）修饰对铜铈催化剂的催化性能有明显的影响.Fe和Co的修饰对铜铈催化剂的CO氧化活性有较明显的促进作用,在110 ℃时,CO的转化率即达到99%；尤其Co的修饰增加了铜铈催化剂上CO转化率为99%的温度‘窗口’宽度约30 ℃,而Mn、Ni和Zn的修饰对铜铈催化剂的CO氧化活性则有一定的抑制作用.但不同过渡金属修饰对铜铈催化剂的氧化选择性均有明显的提高....
