I show ed ha he ac ivi y of ca alys s increased firs and hen decreased wi h increasing Cu/ Zn ra io, among w hich he maximum appeared a Cu/ Zn= 1. From XRD pa ern i show ed ha he charac eris ic peaks of CuO and ZnO of he ca alys ha Cu/ Zn ra io w as 1 w ere he mos dispersed. Addi ion of Zr could increase he ac ivi y and hermal s abili y of ca alys obviously. Addi ion of Mn could increase he hermal s abili y of he ca alys . And addi ion of La and Ce could no influence he ac ivi y much .
