摘要：
环境污染是目前人类面临的严重问题，半导体光催化技术是直接利用太阳能降解有机污染物的方法，有很大的应用潜力。然而大多数半导体光催化剂只能吸收紫外光，对太阳光利用率较低。石墨相碳化氮（g-C3N4）是一种新兴的半导体聚合物材料，无毒副作用、易于制备、能够吸收可见光，受到科研工作者的广泛关注。该文针对g-C3N4及其改性的g-C3N4光催化降解有机污染物应用进行总结和讨论，并对未来的研究方向进行展望。

Abstract: Environmental pollution is a serious problem people face recently. Semiconductor photocatalysis is a potential technology which could directly utilize solar energy to degrade organic pollutants. However, most semiconductor photocatalysts only absorb ultraviolet light and have low utilization efficiency of sunlight. Graphitic carbon nitride (g-C3N4) is an emerging semiconductor material with advantages of no-toxicity and side effects, easy preparation and visible light absorption which attract wide attention of researchers. In this paper, the applications of g-C3N4 and modified g-C3N4 in photocatalytic degradation of organic pollutants are summarized. In addition, the future researches of g-C3N4 based degradation technology are prospected.
