Core/Shell photocatalyst with spatially separated co-catalysts for efficient reduction and oxidation of water.
A simple method allows the preparation of core/shell photocatalysts with spatially separated co-catalysts for efficient water splitting. The high activity was attributed to the core/shell structure and separated co-catalysts that assisted separation and collection of the electrons and holes at the respective co-catalysts, owing to active rectification of electron and hole transport (see picture; Eg =2.1 eV).
