Enhanced Electrochemical Activity of Pt Supported on Three-Dimensional WO3·0.33H2O Networks for Methanol and Ethanol Oxidation
Source abstract
Abstract
Tungsten oxide (WO 3 ·0.33H 2 O) networks and nanorods were prepared by a hydrothermal method. Platinum nanoparticles were distributed on the two types of WO 3 ·0.33H 2 O nanostructures for the methanol and ethanol electrooxidation. The synthesized WO 3 ·0.33H 2 O nanostructures and WO 3 ·0.33H 2 O supported platinum (Pt/WO 3 ·0.33H 2 O) catalysts are characterized by X-ray diffraction, scanning electron microscope and high resolution transmission electron microscope. The electrocatalytic properties of the Pt/WO 3 ·0.33H 2 O composites for the methanol and ethanol oxidation were investigated systematically by typical electrochemical methods and compared with that of Pt supported on carbon nanoparticles. The Pt/WO 3 ·0.33H 2 O network-shaped catalyst shows much higher electrocatalytic activity than that of the other two electrocatalysts as a result of its specific morphology that provides multidimensional active sites and radial channels for liquid diffusion.
