Reinforcing the carrier separation is key issue to maximize photocatalytic hydrogen evolution (PHE) efficiency of graphitic carbon nitride (g-C3 N4 ). By a surface engineering gradual doping graphited rings within g-C3 , suitable energy band structures and built-in electric fields are established. Photoinduced electrons holes impelled into diverse directions, leading 21-fold improvement in PHE rate.
