摘　　要：金属有机骨架(Metal-organic frameworks,MOFs)是由金属节点与有机配体通过配位键连接而成的高度有序的多孔网络框架材料。MOFs具有比表面积大、可设计和调控的结构、主-客体相互作用的性质和强度,在气体吸附、储存、催化、传感、磁学、光学、电化学、药物传输等领域有着巨大的应用潜力,成为近20年来发展最为迅速的一类新型多孔功能纳米材料。开发MOF功能膜器件和装置更需要合成MOF膜而非MOF晶体体相材料,但合成完整、无缺陷的MOF膜仍要面对挑战。合成MOF膜的方法主要有水热合成法、微波合成法、超声合成法、机械球磨法和电化学合成法。电化学合成法快速、在常温常压下进行、化学试剂消耗少,与通常耗时长、不能在常温常压下合成的其他几种方法相比具有明显的优势。本文综述了近10年来电化学合成MOF膜的阳极合成法、阴极合成法、间接双极沉积法、电位移法、电泳沉积法及其应用方面的研究进展,并关注各电化学合成法的优缺点及其在MOF膜制备方法、成膜原理上的差异。Metal-organic frameworks(MOFs)are highly-ordered porous network frameworks constructed from metallic nodes and organic ligands linked together with coordination bonds.MOFs have significant potential applications in gas adsorption,storage,catalysis,sensing,magnetism,optics,electrochemistry,drug delivery,etc.because of their large surface area,designable and tunable structures and nature and strength of host-guest interactions.They have become one of the highest-growing types of functional nanostructured porous solids in the past two decades.MOFs as thin films are much more desirable than MOFs as bulk crystals in the development of MOFs-based components and devices.But the synthesis of defect-free MOF films is still a challenge.The methods for MOF film preparation mainly include hydrothermal synthesis,microwave synthesis,ultrasonic synthesis,mechanical ball milling and electrochemical synthesis.Electrochemical synthesis,usually fast,under environmental temperature and pressure,and with less chemical reagents,has obvious advantages over other methods,which are generally considered as time-consuming and under strict conditions.This paper reviews the relative progress in MOF film electrochemical synthesis techniques,anodic synthesis,cathode deposition,indirect bipolar electrodeposition(IBED),galvanic displacement,and electrophoretic deposition(EDP)and their applications over the last decade and highlight advantages and disadvantages of electrochemical synthesis methods above as well as the differences in their techniques and mechanisms.
