非金属刷状三维氮化碳驱动高效红光光催化
Metal-free brush-like 3D carbon nitride delivers efficient red-light-driven photocatalysis
摘要
Abstract
In this study,melamine and cyanuric acid were used as precursors to form supramolecular crystals via hydrogen-bond-assisted self-assembly followed by hydrothermal treatment.Subsequent high-temperature calcination yielded a novel brush-like three-dimensional carbon nitride.The brush-like 3D architecture was found to expose more accessible active sites,markedly accelerate electron transfer,and suppress the recombination of photogenerated charge carriers.The resulting superoxide(O2-·)and hydroxyl(·OH)radicals generated via electron reduction were identified as the key reactive species in the photocatalytic process.Moreover,the surface of the brush-like structure is enriched with nitrogen vacancies,which enhance the catalyst's ability to harvest visible light.The photocatalytic performance of the brush-like CNS-650 catalyst was evaluated for rhodamine B(RhB)degradation.Under red-light irradiation(660 nm),its degradation rate was 7.4 times higher than that of bulk CN.This work provides valuable insights into the design and application of efficient metal-free 3D photocatalysts.关键词
