摘　　要：非均相催化臭氧氧化可通过直接氧化和生成活性氧物种(ROS)降解水中有机污染物,其净水效能与催化剂性质密切相关.碳基材料因其稳定的化学性质、易于调控的表面特性以及孔结构,在催化臭氧净水方面得到大量研究.基于此,本文系统阐述了近年来碳基催化剂在非均相臭氧氧化净水中的研究进展,详细介绍了常用的碳基催化剂的特性及其功能化调控方法;探讨了碳基材料催化臭氧生成ROS的构效关系、污染物降解的自由基与非自由基反应机制;分析了实际水处理效能与水质条件的影响作用机制;最后对碳基材料催化臭氧净水的未来研究与发展方向进行了展望.结果表明,碳基材料在非均相臭氧氧化净水中具有广阔的应用前景,建议未来研究应聚焦于催化剂优化与实际应用的深入探索.Heterogeneous catalytic ozonation(HCO)was used to degrade organic pollutants in water via both direct oxidation and reactive oxygen species(ROS)converted from ozonation.In general,the physicochemical catalysts properties were considered as an important factor that influenced the wastewater purification efficiency.Being attributed to stable chemical properties,easily regulated surface properties and pore structures,carbon-based materials for HCO arose much attention in wastewater treatment.Herein,the research progress and application of carbon-based catalysts for HCO in wastewater treatment were systematically discussed,which helped reader make a complete view.Furthermore,the functionalization and regulation methods of commonly used carbon-based catalysts were introduced in details,and the relationship between carbon-based materials structure and ROS generation was deeply discussed.Meanwhile,organic pollutants degradation mechanisms via radical and non-radical reaction under different reaction conditions such as water quality were expounded.Finally,the prospection and development of carbon-based materials for HCO in wastewater treatment was proposed.The results showed that carbon-based materials for HCO have broad application prospects in wastewater treatment.Future research should focus on the optimization of catalysts and the in-depth exploration of practical applications.
