Metal-organic frameworks (MOFs) have unique properties but suffer from low conductivity and poor stability, limiting their use in energy storage. Transforming MOFs into other materials, like porous carbon or metal oxides/chalcogenides has been explored to overcome these limitations. However, these approaches still face issues such as dead volume and poor attachment due to insulating binders, causing high resistance and detachment. To address this, MOFs and their derived scaffolds directly on conductive substrates without binders have emerged. These electrodes offer simplified preparation, enhanced electron transfer, and improved interface contact. This mini-review focuses on MOF-derived scaffold electrodes using transition metal oxides, sulfides, selenides, and tellurides, which show promise in energy storage applications. Valuable insights, identified opportunities, and future suggestions in the field of MOF-derived scaffold electrodes and their applications in energy storage applications have been discussed.
金属有机框架材料(MOFs)具有独特的性能,但存在导电性低和稳定性差的问题,这限制了它们在能量存储中的应用。人们已探索将MOFs转化为其他材料,如多孔碳或金属氧化物/硫族化物,以克服这些限制。然而,这些方法仍然面临诸如由于绝缘粘合剂导致的死体积和附着性差等问题,从而导致高电阻和脱离。为了解决这个问题,直接在没有粘合剂的导电基底上的MOFs及其衍生支架应运而生。这些电极具有制备简化、电子转移增强和界面接触改善的特点。本综述聚焦于使用过渡金属氧化物、硫化物、硒化物和碲化物的MOF衍生支架电极,它们在能量存储应用中显示出前景。本文讨论了MOF衍生支架电极领域及其在能量存储应用中的宝贵见解、已发现的机会和未来建议。
