Mesoporous Pt electrocatalyst for methanol tolerant cathodes of DMFC

High activity mesoporous Pt electrocatalyst, having 2D-hexagonal mesostructure, was synthesized using a triblock poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) copolymer (Pluronic F127®) template. The catalyst was characterized for the oxygen reduction reaction (ORR) in a rotati...
