Integrating nitrogen vacancies into crystalline graphitic carbon nitride for enhanced photocatalytic hydrogen production

We report a facile alkali-assisted salt molten method to construct crystalline carbon nitride with rich nitrogen vacancies. Experimental and computational results show that the crystalline structure allows efficient charge transfer and the nitrogen vacancies provide more active sites, resulting in the enhanced photocatalytic hydrogen production. Nitrogen vacancies are integrated into crystalline graphitic carbon nitride to generate more reaction sites for enhanced photocatalytic hydrogen production.
