The effect of base treatment on Au/γ-Al2O3 prepared by either deposition precipitation or impregnation methods was studied. EXAFS results showed that the pH of γ-Al2O3 suspension during deposition didn’t affect the major Au-O coordination

Catalysts of CoOx and Au/CoOx (x is a stoichiometry between 1.00 and 1.33) were prepared to study their catalytic activity towards the CO oxidation. The oxidation state of cobalt ions in these catalysts was evaluated with TPR (the temperature

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
