通过电沉积法在Ti基体上制备具有纳米结构的Pt-Ni和Pd-Ni薄膜,前者呈纳米花瓣形状,厚度为10～20 nm,后者主要由纳米颗粒组成,大小为50～60 nm.XRD测试结果显示,Pt-Ni和Pd-Ni纳米薄膜结晶程度较差.循环伏安法测试薄膜对乙醇电催化氧化的性能,结果表明Pt-Ni和Pd-Ni纳米薄膜可使乙醇起始氧化电位分别负移至-0.74 V和-0.71 V,且在碱性介质中加Ni可提高催化剂的活性和抗毒化性能. The Pt-Ni and Pd-Ni films with nanostructures were prepared by electrodeposition on Ti substrate. The former was in the form of nano-petals and the thickness was 10 ~ 20 nm. The latter mainly consisted of nanoparticles with the size of 50 ~ 60 nm. The results of XRD showed that the crystallinity of Pt-Ni and Pd-Ni nanofilms was poor.The cyclic voltammetry was used to test the electrocatalytic oxidation of ethanol on Pt-Ni and Pd-Ni nanofilms. The results showed that Pt- Potential negative shift to -0.74 V and -0.71 V, respectively, and adding Ni in alkaline medium can improve the catalytic activity and anti-poisoning performance.
