Phosphorus-doped porous carbon nitride for efficient sole production of hydrogen peroxide via photocatalytic water splitting with a two-channel pathway

The P-doped porous carbon nitride achieves photocatalytic water splitting via a two-channel pathway (water oxidation/oxygen reduction reactions) with high H₂O₂ yield of 1968 μmol g⁻¹ h⁻¹ under room temperature and normal pressure without sacrificial agent and cocatalyst.
