Description
Summary:Core-shell nanostructures, where gold nanoparticles of sub 10 nm size are successfully encapsulated inside porous silica spheres, have been prepared. The detailed characterization of the catalyst shows a high surface area and good mesoporosity. The sinter resistance of the catalyst under repeated cycles of the CO oxidation reaction is observed. Au-mesoporous silica core-shell catalysts demonstrating room temperature CO oxidation activity and resistance towards sintering.
