摘要
作为一种非金属光催化材料,石墨相氮化碳(g-C_(3)N_(4))的制备成本低廉且制备工艺简单,但存在电子-空穴复合快速、可见光吸收范围较窄等固有缺陷。为了进一步提升g-C_(3)N_(4)的光催化性能,研究者提出了采用共聚反应、酰胺反应、羟化羧化反应等方式进行化学接枝改性的思路。改性后,光催化材料的固有缺陷得到改善,g-C_(3)N_(4)的光催化性能得到显著增强。本文综述了近年来g-C_(3)N_(4)化学接枝改性取得的进展及成果,旨在为后续研究提供参考。
As a non-metallic photocatalytic material,graphite-phase carbon nitride(g-C_(3)N_(4))was inexpensive and simple to prepare.However,there were inherent defects such as rapid electron-hole complexation and narrow visible light absorption range.To further enhance the photocatalytic performance of g-C_(3)N_(4),researchers proposed the idea of chemical grafting modification by copolymerization,amide reaction,hydroxylation carboxylation reaction,etc.After the modification,the intrinsic defects in the photocatalytic material were improved,and the photocatalytic performance of g-C_(3)N_(4) could be significantly enhance.In this paper,the progress and achievements of chemical grafting modification of g-C_(3)N_(4) in recent years were reviewed intended to provide reference for future research.
