Different template routes were applied for the fabrication of two types of mesoporous tungsten carbide/carbon (WC/C) assisted with a microwave heating method. One was WC/C-F using triblock copolymer Pluronic F127 (PEO106PPO70PEO106) as soft template and the other was WC/C-S using mesoporous silica SBA-15 as hard template. In our study, sucrose was used as the carbon source for both tungsten carbide and carrier carbon. With loading small amount of Pt, two catalysts (Pt-WC/C-F and Pt-WC/C-S) exhibit better performance than the commercial Pt/C for methanol oxidation. Meanwhile the Pt-WC/C-F catalyst presents higher activity and stability than does the Pt-WC/C-S which is ascribed to the appropriate pore size adjusted by the different template routes.
