Contamination of water resources by refractory organic pollutants is of great environmental and health concern because these compounds are not degraded in the conventional wastewater treatment plants. In recent years, sonocatalytic treatment has been considered as a promising advanced oxidation technique for the acceptable degradation and mineralization of the recalcitrant organic compounds. For this purpose, various sonocatalysts have been utilized in order to accelerate the degradation process. The present review paper provides a summary of published studies on the sonocatalytic degradation of various organic pollutants based on the application of carbon-based catalysts, including carbon nanotubes (CNTs), graphene (GR), graphene oxide (GO), reduced graphene oxide (rGO), activated carbon (AC), biochar (BC), graphitic carbon nitride (g-CN), carbon doped materials, buckminsterfullerene (C60) and mesoporous carbon. The mechanism of sonocatalytic degradation of different organic compounds by the carbon-based sonocatalysts has been well assessed based on the literature. Moreover, the details of experimental conditions such as sonocatalyst dosage, solute concentration, ultrasound power, applied frequency, initial pH and reaction time related to each study have also been discussed in this review. Finally, concluding remarks as well as future challenges in this research field regarding new areas of study are also discussed and recommended.
水资源受到难降解有机污染物的污染，这对环境和健康构成了极大的威胁，因为这些化合物在传统的废水处理厂中无法降解。近年来，声催化处理已被认为是一种很有前途的高级氧化技术，可以对难降解有机化合物进行可接受的降解和矿化。为此，已经利用了各种声催化剂来加速降解过程。本文综述了基于碳基催化剂（包括碳纳米管（CNTs）、石墨烯（GR）、氧化石墨烯（GO）、还原氧化石墨烯（rGO）、活性炭（AC）、生物炭（BC）、石墨相氮化碳（g-CN）、碳掺杂材料、富勒烯（C60）和介孔碳）的应用，对各种有机污染物的声催化降解进行了研究。根据文献，对不同有机化合物在碳基声催化剂作用下的声催化降解机制进行了很好的评估。此外，还讨论了与每个研究相关的实验条件的详细信息，如声催化剂用量、溶质浓度、超声功率、应用频率、初始 pH 值和反应时间。最后，还讨论并推荐了该研究领域在新的研究领域中的结论和未来挑战。
