MOF-derived hexagonal In2O3 microrods decorated with g-C3N4 ultrathin nanosheets for efficient photocatalytic hydrogen production

Abstract

This study reported the establishment of a highly efficient In₂O₃@g-C₃N₄ heterostructure with intimate contact for photocatalyzed H₂ evolution by incorporating g-C₃N₄ ultrathin nanosheets on the surface of MOF-derived hexagonal In₂O₃ microrods. As a result, the In₂O₃@g-C₃N₄ composites possessing nanosheet–microrod composite structures exhibited remarkably improved photocatalytic performance in comparison to pure g-C₃N₄ and In₂O₃ photocatalysts for the evolution of hydrogen via the water-splitting process.
