An effective and durable interface structure design for oxygen reduction and methanol oxidation electrocatalyst

In order to inhibit the corrosion of carbon support and agglomeration of Pt nanoparticles in conventional Pt/XC-72 catalyst, the conventional Pt/C catalyst was modified by in-situ deposition of amorphous tungsten carbide (WC) at the catalyst/support interface. The results show that proper amount of WC can improve the performance and durability of catalyst, and excessive addition of W element will combine with oxygen and transform into WO3, thus...
