Abstract

Abstract Reinforcing the carrier separation is the key issue to maximize the photocatalytic hydrogen evolution (PHE) efficiency of graphitic carbon nitride (g‐C 3 N 4 ). By a surface engineering of gradual doping of graphited carbon rings within g‐C 3 N 4 , suitable energy band structures and built‐in electric fields are established. Photoinduced electrons and holes are impelled into diverse directions, leading to a 21‐fold improvement in the PHE rate.
