摘　　要：在过去的几十年中,各种光催化材料和技术的不断发展,为解决日益严重的环境污染问题提供了有效路径。类石墨相氮化碳(g-C3N4)作为一种优良的光催化剂,由于具有独特结构和物化性能,同时还具有合成便捷、性质稳定、原料易得以及清洁无毒等特点,已成为了研究的热点。但由于存在比表面积不大、可见光响应范围窄、光生载流子难分离等缺陷,使得g-C3N4在光催化等领域的应用上受到了很大程度上的限制。因此,研究者们不断寻找合适的方法对g-C3N4进行改性,以增强其光催化效率。本文结合国内外研究成果,介绍了g-C3N4的主要合成制备方法,并对不同改性方法的研究进展进行了总结,最后探讨了今后的研究重点及方向等。In the past decades, the continuous development of various photocatalytic materials and technologies had provided an effective way to solve the increasingly serious environmental pollution problems. As an excellent photocatalyst, graphitic carbon nitride (g-C3N4) had become a research hotspot because of its unique structure and physicochemical properties, convenient synthesis, stable properties, easily available raw materials, cleanness, and non-toxicity. However, due to the defects of small specific surface area, narrow visible light response range, and difficult separation of photogenerated carri-ers, the application of g-C3N4 in photocatalysis and other fields had been extremely limited. Therefore, researchers were constantly looking for suitable methods to modify g-C3N4 to enhance its photocatalytic efficiency. In this paper, the main syn-thesis and preparation methods of g-C3N4 were introduced, and the re-search progress of different modification methods was summarized. Finally, the future research fo-cus and direction were discussed.
