摘　　要：设计和开发高效电催化剂对能源的存储和转化具有十分重要的意义。金属-有机框架(MOF)在基底表面通过液相外延层层配位组装的MOF薄膜(也被称作表面配位MOF薄膜,SURMOF)具有厚度可调节、生长取向可控以及表面均匀致密等优点,在电催化反应领域得到了广泛的研究和应用。本文总结了SURMOF及其衍生薄膜(SURMOF-D)的制备及其在电催化应用中的研究进展。由于SURMOF及其衍生薄膜具有结构多样性和功能可调节性,可在析氧反应、析氢反应、氧化还原反应、二氧化碳还原反应、超级电容器和串联电催化等过程中提供丰富的活性位点并加速电荷转移,使电催化性能更加高效。本文还讨论了SURMOF作为一类新型的薄膜催化剂在电催化应用中的研究挑战和存在的问题。With the increasing demand for energy resources,the development of efficient electrocatalysts has attracted much attention on energy storage and conversion.As a kind of inorganic-organic hybrid materials,recently crystalline metalorganic frameworks(MOF)have been used as electrocatalysts in electrocatalytic reactions due to their abundant metal nodes and organic linkers,high porosity and large surface area.MOF thin films are crucial to achieve effective reactions due to their fast charge transfer and sufficient catalytic sites.Particularly,MOF thin films are coordinated on substrate surfaces by liquid phase epitaxial(LPE)layer by layer(LBL)growth method(called surface-coordinated MOF thin films,SURMOF),which recently have been studied in various fields due to their controlled thickness,preferred growth orientation and homogeneous surface.The backgrounds of electrocatalysis,MOF and SURMOF are briefly introduced at the beginning of this review.Then,the preparation and electrocatalytic applications of SURMOF and their derived thin films(SURMOF-D)are summarized respectively.Owing to the SURMOF based thin films’tunable structures,controllable thickness and growth orientation,strong coordination interaction between MOF and substrate surface,and compact film,they can provide abundant catalytic sites and fast charge transfer for efficient electrocatalytic activities in oxygen evolution reaction(OER),oxygen reduction reaction(ORR),hydrogen evolution reaction(HER),carbon dioxide reduction reaction(CRR),supercapacitor,tandem electrocatalysis and so on.At the end of the review,SURMOF and SURMOF-D for the electrocatalytic applications are also discussed on the current research challenges and problems to be solved.
