By heating g-C3N4 powder in the hydrogen atmosphere, nitrogen defects were introduced into the framework of g-C3N4 where the nitrogen atoms in g-C3N4 were reacted and partially removed with hydrogen. The effects of nitrogen defects on the electronic structure, optical properties, generation of reactive oxygen species and photocatalytic no (cas 116632-23-6) oxidation of g-C3N4 were investigated by combining experimental characterization and DFT theoretical calculations. The N defect is located at N2C sites and can be tuned by the H2 treating temperature. The obtained N defective g-C3N4 products possessed narrower bandgap adjusted by surface N defects and were able to promote the separation of photoexcited charge carries and produce reactive oxygen species more efficiently than pristine g-C3N4. The NO+ reaction intermediate was formed on the N defects sites and enabled an accelerated photocatalytic reaction that contributed to enhanced photocatalytic NO removal. The NO removal ratio on N defects g-C3N4 obtained at 600 ℃ (CH-H-600) was 2.6 times that of pristine g-C3N4 under visible light irradiation. The present work could provide new insights into the understanding of the role of N-defects in g-C3N4 and application of photocatalytic technology for efficient air purification.
