Abstract

This research analyzes the current energy problems and environmental problems and proposes to use hydrogen energy as a clean alternative energy source, which has high energy density and less pollution. After comparing the advantages and disadvantages of various hydrogen storage solutions, metal-organic frameworks (MOFs) are selected as the storage and transportation medium because of its large capacity, favourable reversibility, appropriate reaction conditions and relatively low density. The hydrogen storage mechanism of MOFs and the factors affecting its hydrogen storage capacity are introduced and discuss some methods to improve the storage features of MOFs. Three promising, MOFs, MOF-5, MIL-101 and NU-1501, are listed and their storage performance and specific structure are introduced. The current problems in the application and processing of partial hydrogen storage MOFs are proposed, and some feasible solutions and processing methods are introduced. Finally, the application prospects of MOFs are prospected and suitable development directions are proposed, which will be helpful for future research.
