摘　　要： 以掺C的TiO_2纳米纤维为载体,通过化学还原法制备了一种新型直接甲醇燃料电池阳极催化剂PdRu/TiO_2-C.采用SEM、XRD和电化学分析等对其形貌、结构和电化学性能进行了表征.结果表明,Pd Ru/TiO_2-C纳米纤维催化剂对甲醇具有良好的催化活性,Pd、Ru物质的量比为1∶1时催化剂对甲醇的电催化氧化活性最高. A novel PdRuFFiO2-C nanofiber electrocatalyst was synthesized by the chemical reduction method using carbon doped TiO2nanofiber as support. The pattern, structure and electrochemical performances of the PdRu/FiO2-C nanofiber catalyst were characterized by SEM, XRD and electrochemical analysis. The PdRuFFiO2-C nanofiber elec- trocatalyst has shown promising catalytic activity for methanol electro-oxidation. The electrocatalytic oxidation activity of methanol reached the highest when the mass ratio of Pd and Ru was 1 ： 1.
