Description
Summary:The first use of non‐centrosymmetric Janus Au‐TiO2 photocatalysts in efficient, plasmon‐enhanced visible‐light hydrogen generation is demonstrated. The intense localization of plasmonic near‐fields close to the Au‐TiO2 interface, coupled with optical transitions involving localized electronic states in amorphous TiO2 brings about enhanced optical absorption and the generation of electron‐hole pairs for photocatalysis.
