Pt-Ni与Pd-Ni纳米薄膜的电化学制备和乙醇电催化性能研究
Electrochemical Preparation of Nanostructural Pt-Ni and Pd-Ni Films for Ethanol Electro-Oxidation
摘要
Abstract
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.关键词
