Chemical doping is an effective strategy for modifying the electrochemical properties of polymeric carbon nitride and tuning its visible-light photocatalytic activity. In this study, chlorine-doped polymeric carbon nitride (Cl-PCN) has been synthesized by the polycondensation method. Among a series of samples, 200Cl-PCN exhibited the best photocatalytic activities for the hydrogen evolution from water splitting. Main aspects were revealed: (i) unique location of Cl atoms at the interlayers of PCN instead of on its π-conjugated planes, (ii) slight band gap narrowing, (iii) lower recombination rate of the electron-hole pairs, and (iv) improved photogenerated charge transport and separation. The above factors affected the 4.4-fold enhancement of photocatalytic efficiency in hydrogen evolution in comparison to the pristine catalyst.
