Silver nanoparticles (Ag NPs) of various colors were synthesized within the mesopore structure of SBA‐15 by using microwave‐assisted alcohol reduction. The charge density is partially localized on the surface of these Ag NPs owing to localized surface plasmon resonance. This charge localization results in them having enhanced catalytic activity under visible light irradiation compared to Ag NPs obtained by thermal processes.
