摘要
通过水相还原法制备了负载在碳纳米管上的不同金属比例的Pt-Ag合金催化剂(Pt_(x)Ag_(y)/CNT),并对其在碱性介质中催化1,4-丁二醇氧化的活性进行了研究。电化学测试结果表明,Pt_(x)Ag_(y)/CNT的质量活性高于Pt/CNT,PtAg_(3)/CNT具有最强的催化性能(1081 mA/mgPt);在80℃和-0.43 V的条件下,PtAg_(3)/CNT上γ-丁内酯的收率可达51.4%。
Carbon nanotubes supported Pt-Ag alloy catalysts with different metal ratios(Pt_(x)Ag_(y)/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 Pt_(x)Ag_(y)/CNT are higher than Pt/CNT,and PtAg_(3)/CNT has the best catalytic performance(1081 mA/mgPt).The yields of γ-butyrolactone on PtAg_(3)/CNT can reach 51.4%under 80℃and-0.43 V.
