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

Abstract

The P-doped porous carbon nitride achieves photocatalytic water splitting <italic>via</italic> 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.
