Abstract:		"In this work, LaCoO(3) and LaMnO(3) perovskites with the higher specific surface area were synthesized using MOFs as precursor, then, the composite catalysts CeO(2)-LaCo(x)Fe(y)O(3) and CeO(2)-LaMn(x)Fe(y)O(3) were prepared by using CeO(2) as support and Fe element doping LaCoO(3) and LaMnO(3), respectively. The as-prepared samples were characterized by XRD, SEM, XPS, H(2)-TPR, and N(2) physisorption techniques. Subsequently, toluene was used as the probe molecule for volatile organic compounds (VOCs) to test the catalytic activity of these as-prepared catalysts. The results show that the initial reaction temperature for toluene oxidation on supported perovskite catalysts is lower. Among which, CeO(2)-LaCo(0.25)Fe(0.75)O(3) (T(90)=215 degrees C, T(90): the temperature corresponding to 90% conversion of toluene) and CeO(2)-LaMn(0.25)Fe(0.75)O(3) (T(90)=205 degrees C) catalysts show the best catalytic performance. Therefore, the supported perovskite prepared in this study has the advantages of high specific surface area, abundant oxygen vacancies, and excellent oxygen mobility, which makes it exhibit better performance in VOCs catalytic oxidation"
