Catalytic　reactions　with　different　oxidation　process　were　investigated　and　correlated　to　the　electrochemical　properties　of　the　catalysts.　The　activity　of　suprafacial　reaction　is　closely　related　to　the　area　of　redox　peak,　while　that　of　the　intrafacial　one　is　to　the　match　of　redox　potentials.　Accordingly,　it　is　supposed　that　cyclic　voltammetry　(CV)　measurement　could　be　a　means　for　predicting　the　oxidation　process　in　heterogeneous　catalysis.
