摘　　要：采用水热法合成了PtRu/MWCNTs阳极催化剂,并以循环伏安、线性扫描、计时电流和交流阻抗等电化学测试研究了其对甲醇的电催化氧化,结果表明,水热合成的PtRu/MWCNTs较之同样条件下合成的PtRu/Vu lcan XC-72有更好的对甲醇氧化的催化活性和更强的抗毒化能力。PtRu /MWCNTs anodic catalyst was synthesized by hydrothermal treatment.The electrocatalytic oxidation of methanol was studied by cyclic voltammetry,linear sweep voltammetry,chronoamperometry and impendance spectroscopy.It was found that PtRu/MWCNTs catalysts synthesized in hydrothermal condition had higher electrocatalytic activities and better tolerance to poisoning species in methanol oxidation than that of PtRu/Vulcan XC-72.
