Controllability construction and structural regulation of metal-organic frameworks for hydrogen storage at ambient condition: A review

Due to the active chemical properties of hydrogen at room temperature, the efficient and safe storage technology of hydrogen is the main bottleneck problem in the large-scale application of hydrogen energy, while solid hydrogen storage materials are anticipated to be the solution to the transportation and storage of hydrogen. Similar to normal temperature superconducting materials, solid hydrogen storage materials with excellent hydrogen storage performance under ambient condition are one of the commanding heights of future hydrogen storage technology, which can realize leapfrog effect on the large-scale application of hydrogen energy industry. As a typical adsorptive hydrogen storage material, metal-organic frameworks (MOFs) mostly achieve hydrogen saturated adsorption under the saturated adsorption pressure of 30-300 bar, the research on hydrogen storage performance under ambient condition needs to be further enhanced. In view of the hydrogen storage application of MOFs, the structural controllability of MOFs formed by mainstream synthesis methods, key physical and chemical parameters affecting the hydrogen storage performance and hydrogen storage application of MOFs under ambient condition are analyzed systematically. Furthermore, it provides theoretical support and research prospects for the controllable synthesis strategy of MOFs and the application of hydrogen storage under ambient conditions.
