Ag2O modified g-C3N4 for highly efficient photocatalytic hydrogen generation under visible light irradiation

Abstract

Ag₂O modified g-C₃N₄ (Ag₂O/g-C₃N₄) was synthesized by a facial hydrothermal reaction. The as-prepared Ag₂O/g-C₃N₄ shows efficient photocatalytic properties for hydrogen evolution from water splitting under visible light irradiation. The rate is about 274 times higher than that of pure g-C₃N₄, and is even better than that of Pt/g-C₃N₄. More importantly, Ag₂O/g-C₃N₄ also demonstrates a relatively good recycling stability for photocatalytic hydrogen evolution.
