A facile synthetic strategy for nitrogen-deficient graphitic carbon nitride (g-C N ) is established, involving a simple alkali-assisted thermal polymerization of urea, melamine, or thiourea. In situ introduced nitrogen vacancies significantly redshift the absorption edge of g-C N , with the defect concentration depending on the alkali to nitrogen precursor ratio. The g-C N products show superior visible-light photocatalytic performance compared to pristine g-C N .
建立了一种简便的氮化石墨相碳氮化物（g-C3N4）的合成策略，涉及尿素、三聚氰胺或硫脲的简单碱性辅助热聚合。原位引入的氮空位显著红移 g-C3N4的吸收边缘，缺陷浓度取决于碱与氮前体的比例。与原始 g-C3N4相比，g-C3N4产物表现出优异的可见光光催化性能。
