Abstract

Abstract In this study, we prepared a Pt/C/TiO₂ nanotubes (TiO₂NTs) electrode by the facile pyrolysis of chloroplatinic acid and glucose on the TiO₂NTs support simultaneously. By several characterization methods such as scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, it was found that with the thermal decomposition of H₂PtCl₆ and glucose simultaneously, Pt nanoparticles appeared with small particle size and anchored on the surface of TiO₂NTs with carbon. Cyclic voltammetry and chronoamperometry were used to evaluate the electrocatalytic activity and stability of the prepared electrodes toward the oxidation of methanol. The Pt/C/TiO₂NTs electrode possesses a large electrochemically active surface area and exhibits enhanced electrocatalytic activity and better stability for methanol oxidation than the Pt/TiO₂NTs electrode. The Pt/C/TiO₂NTs electrode provides a new approach for improving the catalytic activity and stability of Pt nanomaterials in renewable energy applications.
