Abstract In this respect, surface photovoltage spectrum (SPV) has been employed to analyze the carrier transfer mechanism of Ti/α-Fe2O3/g-C3N4 composite photocatalyst system for the first time. That is, photo-generated carrier interfacial transfer direction is suggested to be the charge driving force between Ti/α-Fe2O3 and g-C3N4, which could determine the Z-scheme carrier transfer mechanism of Ti/α-Fe2O3/g-C3N4 photocatalysts. This work provides an effective method to understand the Z-scheme carrier transfer mechanism and could help us to design more effective Z-scheme photocatalysts systems.
