Abstract: Disclosed is a method for preparing a composite loaded with nano-magnesium hydride, including: adding a cationic surfactant into an aqueous dispersion of a two-dimensional transition metal carbide such that a nanosheet of the two-dimensional transition metal carbide wrinkles, to avoid re-stacking, and then washing and drying; placing a dried product into a sealed container, vacuuming the sealed container, heating to a high temperature, and holding at the high temperature for a period of time; filling the sealed container with high-pressure hydrogen and holding for a period of time to obtain a heated product; adding the heated product and dibutyl magnesium into an organic solvent, conducting ultrasonic dispersion, then heating under stirring at a hydrogen pressure of 3 MPa to 6 MPa and a temperature of 180° C. to 220° C. for 12 h to 48 h, and centrifuging and drying to obtain the composite loaded with nano-magnesium hydride.
