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-0.71V，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 were successfully prepared on Ti substrates by electrodeposition method. The porous Pt-Ni nanoflakes appeared to be uniform with the thickness of the slices about 10 ~ 20 nm. The porous Pd-Ni nanoparticles with a flower shape appeared to be uniform with the diameters of 50 ~ 60 nm. The XRD patterns also indicated that the Pd-Ni and Pt-Ni nanostructures have the poor crystallinity. The onset potentials of ethanol oxidation were negatively shifted to –0.74 V on Pt-Ni electrodes and –0.71 V on Pd-Ni electrodes, respectively. Addition of Ni could enhance catalytic activities and antitoxic properties of Pt, as well as the electro-catalytic activities of Pd for ethanol oxidation in alkaline media.
