Growth of narrow-bandgap Cl-doped carbon nitride nanofibers on carbon nitride nanosheets for high-efficiency photocatalytic H₂O₂ generation.

ABSTRACT: Heterojunction construction has been proved to be an effective way to enhance photocatalysis performance. In this work, Cl-doped carbon nitride nanofibers (Cl-CNF) with broadband light harvesting capacity were in situ grown on carbon nitride nanosheets (CNS) by a facile hydrothermal method to construct a type II heterojunction. Benefiting from the joint effect of the improved charge carriers separation efficiency and a broadened visible light absorption range, the optimal heterostructure of Cl-CNF/CNS exhibits a H₂O₂ evolution rate of 247.5 μmol g^-1 h^-1 under visible light irradiation, which is 3.4 and 3.1 times as much as those of Cl-CNF (72.2 μmol g^-1 h^-1) and CNS (80.2 μmol g^-1 h^-1), respectiv
