Artificial photosynthetic systems are promising approaches to convert sunlight into chemical fuels.1,2 The most popular strategy is photoelectrochemical(PEC) water splitting to produce hydrogen sustainably.3 Metal oxide composites, typically comprising a primary photon absorbing semiconductor with a secondary semiconductor that may play a number of assisting roles, are constructed using various materials to elucidate the processes of electron-hole separation and charge transport through the composite. These composite structures are divided into four different configurations depending on the possible electron-hole separation mechanism.These systems elucidate the effect of conduction and valence band positions of the individual components of composite materials.
