摘要 采用恒电位法在多孔阳极氧化铝模板中电沉积Pd纳米线阵列,再运用循环伏安法在Pd纳米线阵列表面沉积Pt纳米粒子制备出复合纳米材料电极。运用循环伏安法和计时电流法研究了该复合纳米材料电极对乙醇的电催化性能的影响。结果表明,Pt纳米粒子/Pd纳米线复合电极相比于单独的Pd纳米线电极或Pt纳米粒子电极,对乙醇氧化有更高的电催化活性和很好的稳定性。 Highly ordered Pd nanowire arrays were prepared by electrodeposition method using anodic aluminum oxide（ AAO） tem-plate and Pt nanoparticles were deposited on the Pd nanowire array to prepare nano-Pt/Pd nanowires composite electrode. The elec-trocatalytic activity of ethanol oxidation at nano-Pt/Pd nanowires composite toward electrode was measured by cyclic voltammetry （ CV） and chronoamperometry. The results revealed that nano-Pt/Pd nanowires composite exhibited higher electrocatalytic activity and better stability than that of nano-Pt or Pd nanowire arrays.
