中文摘要
      新污染物(ECs)因其低浓度、难降解、长期残留、生物累积及高毒性从而对生态和人类健康构成严重威胁. 传统的生物和物理化学方法难以将ECs有效去除,电芬顿(EF)作为一种绿色、环保和高效的污染物去除技术,已广泛应用于水处理领域. 其中,发展高效的阴极电极已被证实是最简便易行、成本经济的方法之一,碳质材料因其优异的性能优势而成为最有前途的阴极材料之一. 然而,EF过程在实际应用过程中仍受到氧还原反应能力不足、Fe3+/Fe2+循环效率低以及pH工作范围窄等限制. 因此,需要系统全面地梳理现有的研究成果,以明确碳材料阴极EF技术在ECs降解领域的不足之处. 基于此,全面综述了碳质阴极EF技术在目前遇到的瓶颈问题及相应的解决方法. 主要内容包括为促进H2O2电产生量、增强Fe3+/Fe2+循环效率以及拓宽pH工作窗口所采取的手段及涉及的原理,并对EF技术的实际应用现状进行了阐述. 最后将此类研究存在的一些问题及后续需要重点改善的地方,以及对未来碳阴极EF技术用于ECs降解领域的研究方向提供了展望,可为发展高效的EF技术提供一定的科学依据.
英文摘要
      Emerging contaminants (ECs) pose a serious threat to ecology and human health because of their low concentration, difficult degradation, long-term residue, bioaccumulation, and high toxicity. The traditional biological and physicochemical methods cannot effectively remove ECs. Electro-Fenton (EF), as a green, environmentally friendly and high efficiency means for removing pollutants technology, has been widely used in the field of water treatment. Among them, the development of an efficient cathode electrode has proven to be one of the most simple and cost-effective methods, and carbonaceous materials have become one of the most promising cathode materials because of their excellent performance. However, the EF process is still limited by insufficient oxygen reduction capacity, low efficiency of the Fe3+/Fe2+ cycle, and narrow pH work range in the practical application. Based on this, this paper comprehensively summarizes the bottleneck problems encountered by carbonaceous materials cathode EF technology at present and the corresponding solutions. The main contents include the means and principles involved in promoting the electro-generation of H2O2, enhancing the efficiency of the Fe3+/Fe2+ cycle, and broadening the pH working window, and the practical application status of EF technology is expounded. In the end, some problems existing in this type of research and the areas that need to be improved in the future are listed, and the future research direction of carbonaceous cathode EF technology in the field of ECs degradation is prospected. This will provide a scientific basis for the development of efficient EF technology.
