Abstract

Carbon materials are widely used as catalysts in electrocatalytic oxidative (EO) degradation of wastewater due to their large specific surface area and low cost. Carbon materials can also be used as catalyst carriers for EO reactions due to their ease of functionalization with other heteroatoms and metals/metal oxides. To improve the catalytic activity and current efficiency of carbon materials, modifying the structural and physicochemical properties of conventional carbon materials are common improvement method. This review briefly outlines the recent research progress of carbon materials in EO for organic pollutants degradation. It also discusses the modification strategies and corresponding electrocatalytic properties of various carbon materials (carbon nanomaterials and porous carbon materials), and explores the EO mechanism. Finally, some summaries of the remaining challenges and future developments of carbon materials in the field of electrocatalysis are given.

电催化氧化系统中碳材料处理废水中有机污染物的研究进展

碳材料具有比表面积大、成本低等优点，在电催化氧化降解废水中得到了广泛的应用。由于碳材料易于与其他杂原子和金属/金属氧化物官能化，因此也可以用作EO反应的催化剂载体。为了提高碳材料的催化活性和电流效率，对常规碳材料的结构和理化性质进行改性是常用的改进方法。本文综述了近年来碳材料在EO中降解有机污染物的研究进展。讨论了各种碳材料(碳纳米材料和多孔碳材料)的改性策略和相应的电催化性能，并探讨了电催化机理。最后，对碳材料在电催化领域存在的挑战和未来的发展进行了总结。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
