摘要：

Evenly dispersed Pt-Ni nanoparticles were loaded on TiO(2) nanotube arrays (TiO(2)NTs) via pulse electrodeposition method and subsequently characterized by FESEM, EDX and XRD. The electrochemical studies showed that the catalytic activities of Pt-Ni/TiO(2)NTs are better than that of Pt/TiO(2)NTs for methanol electro-oxidation in alkaline media both in the dark and under illumination. In addition, due to the interaction of electro-catalysis and photocatalysis, the catalytic activities of TiO(2)NTs-based catalysts were improved largely under illumination. Base on the results obtained in this work, Pt-Ni/TiO(2)NTs may be used to develop a base for photo assist direct methanol fuel cell. (C) 2011 Elsevier B.V. All rights reserved.
