The photothermal process has attracted considerable attention in water treatment due to its advantages of low energy consumption and high efficiency. In this respect, photothermal materials play a crucial role in the photothermal process. Particularly, carbonaceous materials have emerged as promising candidates for this process because of exceptional photothermal performance. While previous research on carbonaceous materials has primarily focused on photothermal evaporation and sterilization, there is now a growing interest in exploring the potential of photothermal effect-assisted advanced oxidation processes (AOPs). However, the underlying mechanism of the photothermal effect assisted by carbonaceous materials remains unclear. This review aims to provide a comprehensive review of the photothermal process of carbonaceous materials in water treatment. It begins by introducing the photothermal properties of carbonaceous materials, followed by a discussion on strategies for enhancing these properties. Then, the application of carbonaceous materials-based photothermal process for water treatment is summarized. This includes both direct photothermal processes such as photothermal evaporation and sterilization, as well as indirect photothermal processes that assisted AOPs. Meanwhile, various mechanisms assisted by the photothermal effect are summarized. Finally, the challenges and opportunities of using carbonaceous materials-based photothermal processes for water treatment are proposed.
光热过程因其低能耗和高效率的优点在水处理中受到了广泛关注。在这方面，光热材料在光热过程中起着至关重要的作用。特别是，碳质材料因其卓越的光热性能而成为该过程的有前途的候选材料。虽然先前对碳质材料的研究主要集中在光热蒸发和杀菌方面，但现在人们越来越有兴趣探索光热效应辅助高级氧化过程（AOPs）的潜力。然而，碳质材料辅助的光热效应的潜在机制仍不清楚。本综述旨在全面综述碳质材料在水处理中的光热过程。首先介绍了碳质材料的光热性质，然后讨论了增强这些性质的策略。接着，总结了基于碳质材料的光热过程在水处理中的应用。这包括直接光热过程，如光热蒸发和杀菌，以及辅助AOPs的间接光热过程。同时，总结了光热效应辅助的各种机制。最后，提出了使用基于碳质材料的光热过程进行水处理的挑战和机遇。
