Among the prepared catalysts, Ce/Cuty-Al2O3 showed the highest activity due to its high oxygen vacancy concentration and large amount of reduced Cu species, supported by XPS, Raman, and PL analysis. Additionally, TPR results showed that the catalyst preparation method effected the transformation of bulk CuO species to highly dispersed Cu-species, which influenced the catalyst activity.
