Abstract
Abstract Semiconductor photocatalysts are being recognized as innovative materials for enhancing water quality and environmental optimization. Nevertheless, the limited activity and quick electron–hole pair recombination under visible light have hindered their widespread use in photocatalysis. Nanomaterials based on carbon dots (CDs) show promising applications due to their excellent light absorption ability. Notably, CDs/semiconductor photocatalysts have emerged as advanced photocatalytic materials. This review summarizes strategies to improve the performance of conventional semiconductor photocatalysts by incorporating CDs. These include TiO 2 , g‐C 3 N 4 , Bi‐based, Cu 2 O, and ZnO photocatalysts. Various effective synthesis routes for composites are discussed, including morphology optimization, heteroatom doping, heterojunction building, and creation of polymeric hybrids. Ultimately, the challenges and future prospects of CDs/semiconductor photocatalysts are discussed.
半导体光催化剂是公认的提高水质和优化环境的创新材料。然而，在可见光下有限的活性和快速的电子-空穴对复合阻碍了它们在光催化中的广泛应用。基于碳点的纳米材料具有良好的光吸收能力，具有广阔的应用前景。值得注意的是，CDs/半导体光催化剂已成为先进的光催化材料。本文综述了通过加入CDs来提高传统半导体光催化剂性能的策略。这些催化剂包括tio2, g - c3n4, Bi基，cu2o和ZnO光催化剂。讨论了复合材料的各种有效合成途径，包括形态优化、杂原子掺杂、异质结的建立和聚合物杂化的产生。最后，讨论了CDs/半导体光催化剂面临的挑战和未来的发展前景。
