Polyoxometalates (POMs) have been developed as a class of promising smart material candidates not only due to their multitudinous architectures but also their good redox activities and outstanding electron and proton transport capacities. Recently, abundant studies on POMs composited with metal nanoparticles (NPs), carbon materials (e.g., carbon nanotubes (CNTs), carbon quantum dots (CQDs), graphene), and conducting polymers or highly-porous framework materials (e.g., MOFs, ZIFs) have been performed and POM-based composite materials (PCMs) undoubtedly show enhanced stability and improved electrochemical performances. Therefore, POMs and PCMs are of increasing interest in electrocatalysis, electrochemical detection and energy-related fields (such as fuel cells, redox flow batteries and so on), thus, developing novel PCMs has long been the key research topic in POM chemistry. This review mainly summarizes some representative advances in PCMs with electrochemical applications in the past ten years, expecting to provide some useful guidance for future research.
多金属氧酸盐（POMs）已被开发成为一类有前景的智能材料候选物，这不仅是由于它们具有众多的结构，还因其良好的氧化还原活性以及出色的电子和质子传输能力。最近，人们对将POMs与金属纳米颗粒（NPs）、碳材料（如碳纳米管（CNTs）、碳量子点（CQDs）、石墨烯）、导电聚合物或高孔隙率骨架材料（如金属有机框架材料（MOFs）、沸石咪唑酯骨架材料（ZIFs））复合进行了大量研究，基于POM的复合材料（PCMs）无疑展现出更高的稳定性和更优的电化学性能。因此，POMs和PCMs在电催化、电化学检测及能源相关领域（如燃料电池、氧化还原液流电池等）越来越受到关注，故而，开发新型PCMs长期以来一直是POM化学领域的关键研究课题。本综述主要总结了过去十年中在具有电化学应用的PCMs方面的一些代表性进展，期望能为未来的研究提供一些有益的指导。
