Abstract

Pt-decorated mesoporous silica is directly prepared using a polymeric micelles assembly approach using an asymmetric triblock copolymer, poly(styrene-b-2-vinylpyridine-b-ethylene oxide) as the structure directing agent. Strongly immobilized, fully accessible, and uniformly dispersed Pt nanoparticles on mesoporous silica wall exhibit superior catalytic activity toward CO oxidation.
