摘要:

高级氧化法因其催化降解环境污染物的能力强,且简单快速而备受瞩目。然而该方法虽然催化效率高、适用性强,但仍有很多局限之处亟待解决,如运行成本高、后续处理较复杂等。近年来金属有机框架材料(MOFs)结合高级氧化降解环境污染物的研究增多,可以解决高级氧化法的一些弊病。简要概述了MOFs的分类和合成策略,着重介绍了高级氧化降解污染物的原理以及MOFs催化高级氧化反应的作用原理。系统总结了MOFs结合高级氧化反应在处理环境污染物中的应用,提出了不同种类的MOFs及其复合物可以通过提升分散性、增加不饱和配位数、促进电荷转移等途径以提高其对污染物的去除效果。此外,还对MOFs材料在高级氧化中的发展趋势进行了展望,指出在MOFs性能、复合材料设计以及丰富高级氧化催化方式等方面具有研究前景。

Abstract:

Advanced oxidation progress has attracted much attention because of its strong catalytic ability to degrade environmental pollutants,and its simplicity and speed. However,although this method has high catalytic efficiency and strong applicability,it still has many limitations,such as high operating cost and complicated follow-up treatment. In recent years,more and more studies have been done on the degradation of environmental pollutants with the combination of metal-organic frameworks(MOFs),which can solve some shortcomings of advanced oxidation methods. A brief overview was given of the classification and synthesis strategies of MOFs,with a focus on the principles of advanced oxidation degradation of pollutants and the catalytic effects of MOFs on advanced oxidation reactions. The application of MOFs combined with advanced oxidation reaction in the treatment of environmental pollutants was systematically summarized,and it was proposed that different kinds of MOFs and their complexes could be used to enhance their removal effects on pollutants by improving the dispensability,increasing the number of unsaturated ligands,and promoting the charge transfer. In addition,the development trend of MOFs materials in advanced oxidation was also prospected. It was pointed out that there were research perspectives in the performance of MOFs,the design of composites,and the enrichment of catalytic modes for advanced oxidation.
