【摘要】 采用固相合成的方法制得直接甲醇燃料电池催化甲醇氧化的Pt/MoO3.XRD分析、循环伏安测试表明,Pt/MoO3对甲醇的氧化具有较好的催化作用,氧化峰电位出现在0.63V(vs.SCE),峰电流密度可达78.1mA·cm-2.

【Abstract】 The electrocatalyst, Pt/MoO3 synthesized by solid state reaction, was used for the oxidation of methanol in direct methanol fuel cells. The X-Ray diffraction and cyclic voltammetry were employed to investigate the performance of the material. It was shown that the typical diffraction peaks for Pt appeared in XRD. And a good electrocatalysis for methanol oxidation was observed. The peak potential of the methanol oxidation appeared at ca. 0.63V(vs.SCE) and the peak current density for the oxidation was 78.1 mA cm-2 .
