Heart of gold : A three‐component material composed of 2‐nm Au nanoparticles (see picture; blue spheres) capped with alkanethiols that are partially functionalized with alkoxysilane groups and then incorporated into an “open shell” of silica was prepared. Upon calcination, the sample is a highly active catalyst for the oxidation of CO at low temperatures, being an order of magnitude more active than Au on structured mesoporous materials.
