Abstract
AbstractTungsten oxide (WO3) nanocrystals with the diameter <5 nm supported on porous carbonized resin (denoted as C‐WO3) are synthesized. The WO3 precursors are dispersed at ion level through ion exchange route, then reduced to WO3 nanocrystals. Pt nanoparticles are loaded on the porous C‐WO3 matrix (denoted as Pt/C‐WO3) and used as electrocatalyst in fuel cell for alcohol oxidation, in which WO3 is found efficient promotion effect on Pt electrocatalyst in the electrochemical activity and stability. Thereinto, Pt/C‐WO3 gives 1.63 times higher current densities than the commercial Pt/C (TKK) for methanol oxidation at the same Pt loadings. Moreover, Pt/C‐WO3 electrocatalyst shows excellent properties in mass transfer than Pt/C (TKK). The present method can be readily scaled up for the production of other nanomaterials as well as WO3.
