One-dimensional metal-organic frameworks: Synthesis, structure and application in electrocatalysis

Metal-organic frameworks (MOFs) have been regarded as one of the most promising materials for efficient energy conversion technologies, especially heterogeneous catalysis, since they were initially developed. Recently, one-dimensional (1D) MOFs and their derived materials have shown great potential for electrocatalysis owing to the combination of the characteristics of 1D structure and MOFs, such as favorable charge transfer, adjustable metal center, abundant active sites and porous structure. This review focuses first on the synthesis and structure of 1D MOF materials, and briefly summarizes the application in electrocatalysis. Two main methods, i.e., template-assisted and template-free methods, are introduced by typical examples and the obtained different 1D structures are analyzed. Then the application of 1D MOF and its derived materials are comprehensively described and the structural merits of heterogeneous electrocatalysis are emphasized. Although many 1D MOFs have been developed, exploring a simple and high-yield method to prepare high-crystallized 1D MOF materials for electrocatalysis remains a great challenge. We aim to present the state of the 1D MOFs in the field of electrocatalysis and contribute to the rational design and synthesis of 1D MOFs.
