Exploitation of g-C₃N₄ based photocatalysts capable of drastically boosting photoinduced electron-hole separation and solar-to-H₂ conversion efficiency consequences is a hotspot topic. Herein, a construction of few-layer P-doped g-C₃N₄ (PCN) nanosheets decorated with n-type metal oxides (NMOs) nanostructures, i.e. TiO₂ nanoparticles and SnO₂ nanowires via a self-assembly method is reported. NMOs uniformly distributing on PCN act as electron transporting channels, dramatically enhancing extraction efficiency of photogenerated electrons from PCN. The resultant TiO₂/PCN and SnO₂/PCN in the absence of Pt under visible light irradiation exhibit drastically enhanced H₂ evolution reaction (HER) rates of 1082 and 2090 μmol h⁻¹ g⁻¹ comparing with PCN (132 μmol h⁻¹ g⁻¹). Such HER activities are superb among noble metal-free g-C₃N₄ based photocatalysts. Under a very low Pt amount (0.33 wt%), the HER rates of TiO₂-Pt/PCN and SnO₂-Pt/PCN further climb up to 11,632 and 12,469 μmol h⁻¹ g⁻¹.
