摘要
针对持久性有机物、内分泌干扰物和"三致"物等迫切需要解决的难题逐渐发展起来的臭氧多相催化氧化技术,是利用金属及其氧化物的表面特性强化臭氧分解水中的有毒有害有机污染物。回顾了近二十年来金属氧化物和贵金属催化臭氧降解水中有机污染物的研究现状。与均相催化臭氧氧化及贵金属催化臭氧氧化相比,金属氧化物催化臭氧氧化具有更好的应用前景。结合本课题组的研究成果,按照二氧化钛、锰氧化物、铁氧化物、钴氧化物、氧化铜、氧化锌、其他单一金属氧化物和多组分掺杂金属氧化物等顺序对其催化臭氧机理进行了阐述,并对今后催化臭氧的研究与应用进行了展望。
Heterogeneous catalyzed ozonation technology is developed to removal toxic and harmful organic pollutants in water, including Persistent Organic Pollutants, Endocrine Disrupting Chemicals and Carcinogenieity Mutagenicity Teratogenicity pollutants. The metals and/or metal oxides can accelerate the decomposition of ozone due to their special surface properties thereby promoting the degradation of these pollutants in aqueous solution. The degradation of organic pollutants in aqueous solution by metal oxides and noble metals catalyzed ozonation is reviewed. Metal oxides are more promising in the practical application than metal ions and noble metals in catalytic ozonation. The current research status of metal oxides is described in detail, including titanium dioxides, manganese oxides, iron oxides, cobalt oxides, copper oxides, zinc oxides, other metal oxides with single element and multiple elements metal oxides, along with the results obtained in our groups. The prospect of development on metal oxides and noble metals catalyzed ozonation is presented.
