Abstract: Carbon nanotubes supported Pt-Ag alloy catalysts with different metal ratios (PtxAgy/CNT) are prepared by a facile aqueous-phase reduction method,and their catalytic activities for the oxidation of 1,4-butanediol in alkaline media are studied.It is shown through electrochemical test that as for the electrocatalytic oxidation of 1,4-butanediol,the mass activity of PtxAgy/CNT are higher than Pt/CNT,and PtAg3/CNT has the best catalytic performance (1 081 mA/mgPt).The yields of γ-butyrolactone on PtAg3/CNT can reach 51.4% under 80℃ and -0.43 V.
