摘要
金属有机框架(MOFs)材料作为一种有机-无机杂化材料,有着极高的比表面积和多样化的晶体结构,其可调控的孔隙结构、表面功能化以及丰富的组成使其成为理想的吸附材料.分析了几种类型的MOFs在吸附方面的优势和不足,探讨了孔径、孔道结构、晶胞体积、比表面积、金属节点等晶体结构调控的重要性,并简述了几种合成方法,如水热/溶剂合成法、超声合成法、离子交换法.最后,总结了MOFs对农药残留物、重金属离子、放射性物质的吸附应用进展.
Abstract
Metal-organic frameworks (MOFs),as a kind of organic-inorganic hybrid materials,it has very large specific surface area and diversified crystal structure,and their adjustable pore structure,surface functionalization and rich compo-sition make them ideal adsorption materials. In this paper,the advantages and disadvantages of several types of MOFs in ad-sorption were analyzed,and the importance of crystal structure regulation such as pore size,pore structure,cell volume,specific surface area and metal nodes was discussed. Several synthesis methods,such as hydrothermal synthesis,ionic ther-mal synthesis,ultrasonic synthesis and ion exchange method,were also briefly described. Finally,the application of MOFs to pesticide residues,heavy metal ions and radioactive substances were summarized.
