Integrating Z-scheme heterojunction of Co1-C3N4@α-Fe2O3 for efficient visible-light-driven photocatalytic CO2 reduction

A direct Z-scheme heterojunction of Co₁-C₃N₄@α-Fe₂O₃ was constructed for efficient photocatalytic CO₂ reduction coupled with water oxidation under visible-light irradiation, with a CO generation rate of 14.9 μmol g⁻¹ h⁻¹ and CO selectivity over 99%.
