The synthesis of 3D organic–inorganic hybrid heterojunctions of g-C3N4 nanoneedles@Ti3C2 MXene with superior photocatalytic H2 evolution

Abstract

3D organic–inorganic hybrid heterojunctions of 1D carbon nitride (g-C₃N₄) nanoneedles anchoring on 2D Ti₃C₂ MXene nanosheets have been constructed via a green molten salt treatment. The Ti₃C₂ MXene nanosheets and molten salt treatment guide the formation of ordered nanoneedle-like g-C₃N₄. Both the formed heterojunctions and the nanoneedle-like structures contribute charge separation and transfer for superior photocatalytic H₂ evolution.
