Hydrogen is a clean and sustainable energy carrier, which is considered a promising alternative for fossil fuels to solve the global energy crisis and respond to climate change. Social concerns on its safe storage promote continuous exploration of alternatives to traditional storage methods. In this case, chemical hydrogen storage materials initiate plentiful research with special attention to the design of heterogeneous catalysts that can enhance efficient and highly selective hydrogen production. Metal-organic frameworks (MOFs), a kind of unique crystalline porous materials featuring highly ordered porosities and tailorable structures, can provide various active sites (i.e., metal nodes, functional linkers, and defects) for heterogeneous catalysis. Furthermore, the easy construction of active sites in highly ordered MOFs, which can work as plate for the delicate active site engineering, make them ideal candidates for a variety of heterogeneous catalysts including chemocatalytic hydrogen production. This review concentrates on the application of MOFs as heterogeneous catalysts or catalyst supports in chemocatalytic hydrogen production. Recent progresses of MOFs as catalysts for chemocatalytic hydrogen production are comprehensively summarized. The research methods, mechanism analyses, and prospects of MOFs in this field are discussed. The challenges in future industrial applications of MOFs as catalysts for hydrogen production are proposed.
氢气是一种清洁、可持续的能源载体,被认为是化石燃料的一种有前途的替代品,可以解决全球能源危机和应对气候变化。社会对其安全储存的关注促使人们不断探索替代传统储存方法的方案。在这种情况下,化学储氢材料引发了大量研究,特别关注设计能够增强高效、高选择性制氢的多相催化剂。金属-有机骨架(MOFs)是一种独特的晶体多孔材料,具有高度有序的孔隙率和可调节的结构,可以为多相催化提供各种活性位点(例如金属节点、功能连接体和缺陷)。此外,高度有序的 MOFs 中活性位点的易于构建可以作为精细活性位工程的基础,使它们成为各种多相催化剂的理想候选者,包括化学催化制氢。本文综述了 MOFs 在化学催化制氢中作为多相催化剂或催化剂载体的应用。全面总结了 MOFs 作为化学催化制氢催化剂的最新进展。讨论了该领域 MOFs 的研究方法、机制分析和前景。提出了 MOFs 作为制氢催化剂在未来工业应用中面临的挑战。
