[0002] Hydrogen energy is a secondary energy with abundant sources, green and low carbon, and wide application. It is considered to be the ultimate energy to promote sustainable development of global energy. In the development of the hydrogen energy industry, the storage and transportation of hydrogen is the key link between upstream hydrogen production and downstream hydrogen use. At present, there are three ways to store and transport hydrogen: high-pressure gas, liquid and solid. Among them, solid hydrogen storage has the advantages of high volume hydrogen storage density, good safety, and long storage time. It is considered to be the most promising hydrogen storage technology. Solid-state hydrogen storage refers to the use of materials to store hydrogen in solid materials by physical adsorption and chemical adsorption of hydrogen. The physical adsorption mechanism refers to the reversible adsorption of hydrogen molecules on porous materials with high specific surface area through van der Waals forces. In the chemical adsorption mechanism, hydrogen is generally combined with other elements by ionic bonds or covalent bonds to generate materials such as metal hydrides, which reversibly absorb and release hydrogen under certain conditions. In the existing technology, the capacity of physical adsorption substances is low, the hydrogen storage capacity is not high enough, and the contact efficiency between physical adsorption substances and hydrogen is low, resulting in a decrease in adsorption efficiency.
