摘要

石墨相氮化碳(g-C₃N₄)是一种典型的碳基无金属光催化剂,具有低成本和环境友好的显著优点,逐渐成为催化和环境等领域的研究热点。然而,g-C₃N₄存在电导率低、电荷载流子复合率高等固有缺陷,基于g-C₃N₄的改性研究以提高其光催化性能已成为研究者的主要工作。对近年来有关g-C₃N₄的改性策略进行系统总结,主要包括结构微调和复合体系构建,并对其在光解水产氢、CO₂还原、环境污染物去除等环境领域的应用进行总结,对目前工作中存在的问题及未来发展方向进行了展望。

Abstract

Graphitic carbon nitride (g-C₃N₄) is a typical carbon-based metal-free photocatalyst with significant advantages of low cost and environmental friendliness,which has gradually become a research hotspot in the fields of catalysis and environment.However,g-C₃N₄ suffers from inherent defects such as low conductivity and high charge carrier complexation rate,so the modification studies based on g-C₃N₄ to improve its photocatalytic performance have become a main focus for researchers.In this paper,the modification strategies concerning g-C₃N₄ in recent years were systematically summarized,mainly including structure fine-tuning and composite system construction,and their applications in environmental fields such as photolysis of hydrogen production in water,CO₂ reduction,and removal of environmental pollutants were summarized,with an outlook of the problems in the current work and the future development direction.
