Innovative and efficient strategies are urgently needed for wastewater treatment and environmental remediation. The photocatalytic degradation properties of photo-responsive nanomaterials (NMs) have become a prime candidate due to their low negative impact and photo-adjustability. Photocatalytic NMs vary in their degradation of different pollutants depending on the type of synthetic material, excitation light source, and physicochemical properties. Essentially, photocatalytic NMs excited by light produce reactive oxygen species (ROS) or metal ions that can degrade complex structure pollutants. Therefore, this review summarises the recent advances of photocatalytic NMs in the environmental application within the last 3 years, focusing on the development schemes, structural analyses, photocatalytic mechanisms, and the degradation effects of dyes, antibiotics, pesticides, phenolic compounds, metals, hormones, and other contaminants. The limitations and future directions are also explained. This review hopes to provide a possible pathway for the subsequent development of novel and efficient photocatalytic NMs to cope with complex and variable polluted environments.
需要创新和高效的策略来进行废水处理和环境修复。由于光响应纳米材料（NMs）的负面影响低且可光调节，因此其光催化降解性能成为首选。光催化 NMs 因其合成材料、激发光源和物理化学性质的不同，对不同污染物的降解能力也有所不同。本质上，受光激发的光催化 NMs 会产生具有降解复杂结构污染物能力的活性氧（ROS）或金属离子。因此，本综述总结了过去 3 年中光催化 NMs 在环境应用方面的最新进展，重点介绍了开发方案、结构分析、光催化机制以及对染料、抗生素、农药、酚类化合物、金属、激素和其他污染物的降解效果。还解释了其局限性和未来方向。本综述希望为后续开发新型高效光催化 NMs 以应对复杂多变的污染环境提供一条可行的途径。
