摘要
非均相电芬顿技术是近年来快速发展且极具应用前景的水处理高级氧化技术,其阴极材料的过氧化氢产能与芬顿催化活性是影响该技术实际性能的关键因素。文章基于针对多种非均相电芬顿技术的调研,总结了阴极中碳材料氧还原催化剂的多种催化机理,分析了其中非均相芬顿催化剂性能的限制因素,并指出了当2种活性组分复合时两者性能间可能产生的相互影响。在此基础上,提出了电极复合材料的改良途径与方法,并展望了阴极材料的发展前景。
Heterogeneous electro-Fenton technology is a rapidly developing and promising advanced water treatment technology.The hydrogen peroxide production and Fenton catalytic activity of the cathode material are the key factors affecting the actual performance of the technology.Based on the investigation of various heterogeneous electro-Fenton technology,the various catalytic mechanisms of carbon-material oxygen reduction catalysts in cathodes are summarized.The limiting factors for the performance of heterogeneous Fenton catalysts are analyzed,and the possible interactions between the properties of the two combined active components are pointed out.On this basis,some methods to improve the electrode composites are proposed,and the development of cathode materials is prospected.
