Abstract
A facile method to prepare well-dispersed Platinum nanoparticles (Pt NPs) on FTO and TiO2 nanotube (TNTs) film was reported. The so-prepared Pt/FTO and Pt/TNT film electrodes are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD). The results show Pt NPs have been dispersed on the supporting matrixs uniformly. Electrochemical investigations indicate that Pt/TNT has higher electrocatalytic activity and better tolerance to poisoning species in methanol oxidation than Pt/FTO, which can be ascribed to the high dispersion of Pt NPs on the TiO2 nanotubes surface. The present method is promising for the design of high performance catalysts for direct methanol fuel cells.
