金属有机框架应用于模拟酶的研究进展

Recent advances in the application of metal-organic frameworks to mimic enzymes

金属有机框架(MOFs)是一种由金属离子或金属簇和双齿或多齿配体自组装得到的有序多孔晶体材料,其具有比表面积大、孔径可调、结构多样和表面易修饰等特点,在气体吸附、光电催化、催化剂负载、药物释放等领域有着丰富的应用。模拟酶(mimic enzymes)是用人工方法合成的具有酶性质的一类催化剂。本文简要综述了多种金属有机框架材料(包括铁基、铈基及贵金属基MOF材料)在模拟酶研究领域的研究及应用进展。

Metal-organic frameworks(MOFs)are ordered porous crystal materials which are self-assembled by metal ions or metal clusters and bidentate or multidentate ligands.Due to their large specific surface area,adjustable pore size,diverse structure and easy modified surface,MOFs have been widely used in gas adsorption,photoelectric catalysis,catalyst loading,drug release and other fields.Mimic enzyme is a kind of catalyst synthesized by artificial method,and maintained enzyme-liked properties.In this paper,the application and research progress of metal-organic frameworks(including Fe-based,Ce-based and noble-metal based MOFs)in mimic enzyme were reviewed in short.
