Abstract
An electroless copper plating method, an impregnation method, and a precipitation method were used to prepare copper/alumina catalysts with different loadings. Temperature-programmed reduction (TPR) was employed to characterize the reducibility of copper catalysts prepared by different methods. The experimental results showed that the copper catalyst prepared by electroless plating method had the lowest reduction temperature, followed by the catalyst prepared by the precipitation method, and the catalyst prepared by the impregnation method had the highest reduction temperature.
