Embodiment 1
[0033] Mix the molecular sieve and the ferrous sulfate solution with a mass fraction of 2% evenly, take it out after standing for 1 day, and let it dry naturally at room temperature to obtain the pretreated molecular sieve, and place the pretreated molecular sieve in a chemical vapor deposition furnace for deposition treatment. The green body is obtained, the green body is heat-treated, cooled to room temperature, and the substrate is obtained; the filler is obtained by sputtering on the surface of the substrate; the magnesium hydride and the filler are mixed and placed in a ball mill tank, and ball milling is performed periodically The mixed material is obtained; the mixed material is placed in a reaction tube, subjected to hydrogen absorption and desorption treatment, and cooled to room temperature to obtain a magnesium-based nanocomposite hydrogen storage material. The mass ratio between molecular sieve and 2% ferrous sulfate solution is 1:10. The deposition process steps a...
