The synthesized ZrO2/g-C3N4 composites exhibit superior performance in water splitting for hydrogen production due to the effective electron–hole separation at the composite interface.

In this study, we prepared carbon self-doped carbon nitride nanosheets through a glucose synergic co-condensation method. In the carbon self-doped structure, the N atoms in the triazine rings were substituted by C atoms, resulting in enhanced visible-light photocatalytic hydrogen production, which is three-times higher than that of bulk carbon nitride. The enhanced photocatalytic hydrogen production was attributed to the higher charge-carrier transfer rate and widened light absorption range of the carbon nitride nanosheets after carbon self-doping. Thus, this work highlights the importance of carbon self-doping for improving the photocatalytic performance. Meanwhile, it provides a feasible method for the preparation of carbon self-doped carbon nitride without destroying the 2D conjugated backbone structures.

Abstract Hydrogen production from water splitting via photocatalytic reactions can be an alternative clean energy of fossil fuels in the future. Graphitic carbon nitride (g-C3N4) is one of the active photocatalysts in the visible light region that can be combined with other semiconductors in order to increase its photocatalytic efficiency. TiO2 is one of the most appropriate choices to combine with g-C3N4 because of its conduction band edge and variety forms of nanostructures. In this work, nanosheets of g-C3N4 were mixed with the nanoparticles of titanate in order to enhance charge separation and photocatalytic efficiency. Consequently, the hydrogen evolution of this novel nanocomposite produced almost double hydrogen in comparison with g-C3N4.

Protonated ordered mesoporous carbon nitride acts as a host scaffold that forms an assembly with anionic [Mo3S13]2− clusters by taking advantage of electrostatic interactions to construct an artificial photosynthetic architecture for hydrogen production with visible light.
