With the urgent demand for the achievement of carbon neutrality, novel nanomaterials, and environmentally friendly nanotechnologies are constantly being explored and continue to drive the sustainable development of energy storage and conversion installations. Among various candidate materials, metal-organic frameworks (MOFs) and their derivatives with unique nanostructures have attracted increasing attention and intensive investigation for the construction of next generation electrode materials, benefitting from their unique intrinsic characteristics such as large specific surface area, high porosity, and chemical tunability as well as the interconnected channels. Nevertheless, the poor electrochemical conductivity severely limits their application prospects, hence a variety of nanocomposites with multifarious structures have been designed and proposed from different dimensionalities. In this review, recent advances based on MOFs and their derivatives in different dimensionalities ranging from 1D nanopowders to 2D nanofilms and 3D aerogels, as well as 4D self-supporting electrodes for supercapacitors are summarized and highlighted. Furthermore, the key challenges and perspectives of MOFs and their derivatives-based materials for the practical and sustainable electrochemical energy conversion and storage applications are also briefly discussed, which may be served as a guideline for the design of next-generation electrode materials from different dimensionalities.
随着实现碳中和的迫切需求，新型纳米材料和环境友好型纳米技术不断被探索，并持续推动储能和转换装置的可持续发展。在各种候选材料中，具有独特纳米结构的金属有机框架（MOF）及其衍生物因其独特的内在特性，如大比表面积、高孔隙率、化学可调控性以及相互连接的通道，在构建下一代电极材料方面受到了越来越多的关注和深入研究。然而，其较差的电化学导电性严重限制了它们的应用前景，因此人们从不同维度设计并提出了多种具有多样结构的纳米复合材料。在这篇综述中，总结并突出了基于MOF及其衍生物在从一维纳米粉末到二维纳米薄膜、三维气凝胶以及用于超级电容器的四维自支撑电极等不同维度的最新进展。此外，还简要讨论了基于MOF及其衍生物的材料在实际和可持续电化学能量转换与存储应用中的关键挑战和前景，这可为从不同维度设计下一代电极材料提供指导。
