Photocatalysis is a green approach frequently utilised to eliminate a variety of environmentally hazardous refractory pollutants. Accordingly, the modification of semiconductor photocatalysts with Carbon Quantum Dots (CQDs) is of great importance for the treatment of such pollutants due to their attractive physical and chemical properties. CQDs are a perfect candidate to handle photocatalysts of high-performance since they operate as co-catalysts and as visible light harvesters. The higher separation rate of electron-hole pairs in the photocatalytic system is attributable to better photodegradation efficiency. This review classifies CQD based photocatalysts as pure, doped and composite materials and discusses the specific advantages of CQDs in visible light-driven photocatalysis. In this work, the versatile roles of CQDs in CQD-based photocatalytic systems are thoroughly discussed and summarised.
光催化是一种常用的绿色方法，用于消除各种环境危害的难处理污染物。因此，用碳量子点（CQDs）对半导体光催化剂进行改性对于处理此类污染物非常重要，因为它们具有吸引人的物理和化学性质。CQDs 是处理高性能光催化剂的理想选择，因为它们可以作为助催化剂和可见光收集器。在光催化系统中，电子-空穴对的更高分离率归因于更好的光降解效率。本综述将基于 CQD 的光催化剂分类为纯、掺杂和复合材料，并讨论了 CQDs 在可见光驱动光催化中的特定优势。在这项工作中，彻底讨论和总结了 CQDs 在基于 CQD 的光催化系统中的多种作用。
