MOFs改性材料及其耦合技术活化PS的应用研究

Application of MOFs Modified Material and Its Coupling Technology to Activate PS

金属有机框架(MOFs)具有层次化的多孔结构,其分散良好的金属组分可为催化反应提供足够的活性中心,在基于过硫酸盐的高级氧化技术中,MOFs是一种性能优良的催化剂,具有极大的发展潜力。为提高该材料活化过硫酸盐(PS)的应用效果,通过对MOFs结构改性、MOFs与其他功能材料复合和MOFs与其他技术耦合3个方面进行研究,发现其在活化PS降解有机污染物过程中表现更出色,在提高材料稳定性、减少金属离子溶出、使材料易于分离以及提高选择性上取得了一定进展。

The Metal-Organic Frameworks(MOFs)has a layered porous structure,and its well-dispersed metal components can provide enough active sites for catalytic reaction.MOFs is a good catalyst in persulfate-based advanced oxidation technology,it has great potential for development.In order to improve the application effect of activated persulfate(PS),through the study of structural modification of MOFs,compounding of MOFs with other functional materials and coupling of MOFs with other technologies,it is found that it performs better in the process of degradation of organic pollutants by activated PS,and some progress has been made in improving material stability,reducing metal ion dissolution,making materials easy to separate and improving selectivity.
