Abstract: The methanol electrocatalytic oxidation performance of Pt/RuO2/CNTs nanocata lyst is strongly dependent on the RuO2 content. The specific capacitance change of R uO2/CNTs is the main reason for the change of methanol electrocatalytic activi ty . The Pt/RuO2/CNTs catalyst with 15%Pt and 9.5%RuO2 has the best methanol e lectrocatalytic oxidation activity.
