Fabrication of Bi2WO6 quantum dots/ultrathin nanosheets 0D/2D homojunctions with enhanced photocatalytic activity under visible light irradiation

Bi2WO6 quantum dots and Bi2WO6 nanosheets form a unique zero-dimensional (0D)/two-dimensional (2D) homojunction. This structure promotes the transfer and separation of photogenerated electron-hole pairs, which greatly enhances the photocatalytic activity.
