Abstract
Tungsten carbide microspheres comprising an outer shell and a compact kernel have been synthesized by a simple hydrothermal method and exhibit very high surface area promoting a high dispersion of platinum nanoparticles. Tungsten bronze formation in surface of these WC microspheres was clearly identified by combination of electrochemical characterization and XPS measurements. The presence of a tungsten bronze layer at the surface of a WC core leads to a higher electrochemically active surface area (EAS) stability compared to that of the usual Pt/C electrocatalysts used for PEMFC.
