摘要
金属有机骨架(MOF)材料是一种新型多孔纳米材料,因其具有比表面积高、热稳定性好、种类多样、结构可调等诸多优点,在分离技术方面显示出巨大前景。详细介绍了MOF材料的特性、合成方法以及近年来在环境工程领域的应用情况。MOF材料主要用途为吸附分离具有温室效应的气体(如甲烷、二氧化碳等)以及二氧化硫、挥发性有机物等其他有害气体;还可用于处理含药物、染料、酚类大分子等的有机废水以及含无机阴离子和重金属阳离子等的无机废水。
Metal-organic frameworks,known as a new class of nanoporous materials with large surface area,superior thermal stability,various species,adjustable structure,have wide spread application prospects in the field of separation technology.The characteristics and synthetic methods of metal-organic frameworks were introduced,and the applications of metal-organic frameworks in environmental engineering were reviewed.The main uses of metal-organic frameworks were adsorption and separation on gases with greenhouse effect,such as methane,carbon dioxide and so on,and sulfur dioxide,volatile organic compounds and other harmful gases.Meanwhile,the metal-organic frameworks could be used in the treatment of wastewater,including organic wastewater containing harmful substances such as pharmaceuticals,dyes,phenols,and inorganic wastewater containing inorganic anions and heavy metal ions.
