Catalytic oxidation of ethyl acetate over LaBO(3) (B = Co, Mn, Ni, Fe) perovskites supported silver catalysts

A series of silver catalysts supported on lanthanum based perovskites LaBO(3) (B = Co, Mn, Ni, Fe) were synthesized and evaluated in the catalytic oxidation of ethyl acetate. XRD, BET, TEM/HRTEM, HAADF-STEM, XPS and H(2)-TPR were conducted, and the results indicate that redox activity of the catalysts is of great importance to the oxidation reaction. Activity tests demonstrated that Ag/LaCoO(3) was more active than the other samples in ethyl acetate oxidation. Moreover, the CO(2) selectivity, CO(x) yields and byproduct distributions for all catalysts were studied, and Ag/LaCoO(3) showed the best catalytic performance. Besides, Ag/LaCoO(3) also showed excellent catalytic activity for other OVOCs.
