Abstract

A facile strategy to fabricate modified g-C₃N₄ with all-carbon aromatic rings incorporated in the constitutive plane was presented. The light absorption, band structure and photo-induced carrier separation of this benzene doped g-C₃N₄ was extremely improved. It exhibited a 3 times higher hydrogen evolution rate (HER) and a 17 times higher HER per surface area.
