Facile in situ reductive synthesis of both nitrogen deficient and protonated g-C₃N₄ nanosheets for the synergistic enhancement of visible-light H₂ evolution.

ABSTRACT: A new strategy is reported here to synthesize both nitrogen deficient and protonated graphitic carbon nitride (g-C₃N₄) nanosheets by the conjoint use of NH₄Cl as a dynamic gas template together with hypophosphorous acid (H₃PO₂) as a doping agent. The NH₄Cl treatment allows for the scalable production of protonated g-C₃N₄ nanosheets. With the corresponding co-addition of H₃PO₂, nitrogen vacancies, accompanied by both additional protons and interstitially-doped phosphorus, are introduced into the g-C₃N₄ framework, and the electronic bandgap of g-C₃N₄ nanosheets as well as their optical properties and hydrogen-production performance can be p
