[Display omitted] •Controlled synthesis of a core–shell structure is established to yield various Pt@SiO2 samples.•Turnover frequency for CO oxidation is higher for Pt@SiO2 core–shell catalysts than for Pt/SiO2-supported catalysts.•The SiO2 shell plausibly functions as a membrane leading to a distin...
