Rapid and high-yield production of g-C3N4 nanosheets via chemical exfoliation for photocatalytic H2 evolution

Abstract

Rapid and high-yield production of graphitic carbon nitride (g-C₃N₄) nanosheets was realized by simply adding water into a H₂SO₄ suspension of bulk g-C₃N₄, and the as-prepared nanosheets exhibit enhanced photocatalytic H₂ evolution. Notably, the degree of exfoliation can be controlled by the amount of water to facilitate diverse applications of nano-sized g-C₃N₄.
