金属有机骨架(MOFs)和MXenes在先进材料研究的队列中占有重要地位。这两种材料突出的物理和化学特性突出地促进了它们在不同领域的利用,尤其是电化学储能(EES)领域。极高的比表面积(SSA)的集体贡献,可定制的毛孔,和丰富的活性位点提出MOFs作为EES设备的整体材料。然而,传统的MOFs承受低电导率,限制了它们在实际应用中的效用。通过将MOFs与各种导电材料集成在一起开发混合材料是提高MOF导电性的有效途径。MXenes,配制为过渡金属的二维(2D)碳化物和氮化物,属于最新的2D材料类别。MXenes具有广泛的结构多样性,令人印象深刻的导电性,和丰富的表面化学特性。MOF@MXene杂化的电化学特性分别优于MOF和MXenes,归功于这两个组成部分的协同作用。此外,与MXene偶联的MOF衍生物,表现出独特的形态,表现出优异的电化学性能。MOF@MXene杂种的重要属性,包括各种合成方案,在这篇综述中进行了总结。这篇综述深入研究了MOF和MXenes的架构分析,以及他们先进的混合动力车。此外,对MOF@MXene杂化作为超级电容器(SC)的电活性材料的最新进展的全面调查是这篇综述的主要目标。本综述最后详细讨论了当前面临的挑战以及优化MOF@MXene复合材料的未来前景。
Metal-organic frameworks (MOFs) and
MXenes have gained prominence in the queue of advanced material research. Both materials\' outstanding physical and chemical characteristics prominently promote their utilization in diverse fields, especially the electrochemical energy storage (EES) domain. The collective contribution of extremely high specific surface area (SSA), customizable pores, and abundant active sites propose MOFs as integral materials for EES devices. However, conventional MOFs endure low conductivity, constraining their utility in practical applications. The development of hybrid materials via integrating MOFs with various conductive materials stands out as an effective approach to improvising MOF\'s conductivity.
MXenes, formulated as two-dimensional (2D) carbides and nitrides of transition metals, fall in the category of the latest 2D materials.
MXenes possess extensive structural diversity, impressive conductivity, and rich surface chemical characteristics. The electrochemical characteristics of MOF@MXene hybrids outperform MOFs and
MXenes individually, credited to the synergistic effect of both components. Additionally, the MOF derivatives coupled with MXene, exhibiting unique morphologies, demonstrate outstanding electrochemical performance. The important attributes of MOF@MXene hybrids, including the various synthesis protocols, have been summarized in this review. This review delves into the architectural analysis of both MOFs and
MXenes, along with their advanced hybrids. Furthermore, the comprehensive survey of the latest advancements in MOF@MXene hybrids as electroactive material for supercapacitors (SCs) is the prime objective of this review. The review concludes with an elaborate discussion of the current challenges faced and the future outlooks for optimizing MOF@MXene composites.
