g-C₃N₄ is a hot visible light photocatalyst. However, the fast recombination of photogenerated electron-hole pairs leads to unsatisfactory photocatalytic efficiencies. In this study, Mg/O co-decorated amorphous carbon nitride (labeled as MgO-CN) with a unique electronic structure was designed and prepared via a combined experimental and theoretical approach. The results showed that the MgO-CN exhibited an increased light absorption ability and promoted charge separation efficiency. The Mg and O co-decoration created a unique structure that could generate localized electrons around O atoms and enhance the reactant activation capacities via the C→O←Mg route. This could dramatically promote the O₂ molecule activation on the catalyst surface to generate reactive species (·O₂^-/·OH). The optimized MgO-CN exhibited a high photocatalytic activity for the degradation of tetracycline hydrochloride in water, which was five times higher than that of pristine g-C₃N₄. The present work could provide a new strategy for modifying the electronic structure of g-C₃N₄ and enhancing its performance for environmental applications.
