With the increasingly serious environmental problems caused by fossil fuels, hydrogen energy, which has advantages such as high calorific value, renewability, and zero carbon emissions, has been given high expectations [1][2][3][4] . Hydrogen energy not only provides power for hydrogen fuel cell vehicles (HFCVs) [5] , but also plays a crucial role in industrial fields such as chemicals, electronics, and power [6] . At present, the main obstacle to the widespread application of hydrogen energy is its storage and transportation [7] . The current mainstream hydrogen storage methods are high-pressure gaseous hydrogen storage, lowtemperature liquid hydrogen storage, and metal hydride solid-state hydrogen storage [8][9][10] . Metal hydride solid-state hydrogen storage has received widespread attention due to its high safety and high hydrogen storage density [11][12][13] . In the past few decades, a series of solid-state hydrogen storage materials have been developed [10][11][12][13][14][15][16] , but these materials cannot simultaneously meet the requirements of easy activation, fast absorption and release rates, high hydrogen storage capacity, and working close to room temperature and atmospheric pressure.
