生物炭光催化降解有机污染物的研究进展

Research Progress of Biochar Photocatalytic Degradation of Organic Pollutants

有机污染物是水环境中常见的污染物,部分具有持久污染性,可致癌、致畸、致突变,处理和降解这些有机污染物已经成为人们广泛关注的问题。生物炭可催化降解有机污染物,减少其环境风险。因此,本文主要综述生物炭的性质及其光催化降解有机污染物的机理,将先前研究的光催化降解机理关系图转化为比较直观的光反应方程式,为相关研究者提供参考。

Organic pollutants are common pollutants in the water environment,and some of them have persistent pollution,which can cause cancer,teratogenicity and mutagenesis,and handling and degrading these organic pollutants has become a widespread concern.Biochar can catalytically degrade organic pollutants and reduce their environmental risks.Therefore,this paper mainly reviews the properties of biochar and its photocatalytic degradation mechanism of organic pollutants,and converts the photocatalytic degradation mechanism diagrams of the previous studies into more intuitive photoreaction equations,so as to provide reference for relevant researchers.
