1. A method for preparing a composite loaded with nano-magnesium hydride, comprising:
step (1):
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 obtain a wrinkled two-dimensional transition metal carbide, and
washing and drying the wrinkled two-dimensional transition metal carbide to obtain a dried product;
step (2):
placing the dried product obtained from step (1) into a sealed container, vacuuming the sealed container, heating the dried product to a temperature of 600° C. to 1,000° C., and holding the dried product at the temperature for 2 h to 5 h to obtain a heated product, and
filling the sealed container with 1 MPa to 10 MPa of hydrogen and holding the heated product for 2 h to 5 h to obtain a product; and
step (3):
adding the product obtained from step (2) and dibutyl magnesium into an organic solvent to obtain a mixture,
subjecting the mixture to ultrasonic dispersion to obtain a dispersion mixture,
heating the dispersion mixture 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 to obtain a heated dispersion mixture, and
centrifuging and drying the heated dispersion mixture to obtain the composite loaded with nano-magnesium hydride.
