Synthesis and characterization of Cu2O/TiO2 photocatalysts for H2 evolution from aqueous solution with different scavengers

- Cu2O/TiO2 photocatalyst are prepared by a facile ethanol reduction method.
- The heterojunction between p-type Cu2O and n-type TiO2 improves activity of TiO2.
- An optimal molar fraction of Cu2O is reported in Cu2O/TiO2 photocatalysts.
- The effect of different alcohols scavengers on activity of Cu2O/TiO2 is discussed.
