The physical and chemical properties of the catalysts were characterized using BET, XRD,TEM, XPS and CO-DRIFT techniques. It was found that the non-crystallized CuNiMnZrO2 catalyst demonstrated highly dispersed active phases and high activity for CO adsorption, which resulted in good performance for synthesis of higher alcohols in CO hydrogenation compared to crystallized CuNiMnZrO2. 关 键 词：CuNiMnZrO2 催化剂 CO 一氧化碳 加氢反应 锰镍铜锌复合氧化物 溶胶-凝胶 合成 高浓度乙醇
