description The invention provides a carbon magnesium base composite hydrogen storage material and a preparation method thereof. The preparation method comprises the following steps: (1) magnesium powder, lanthanum powder and cerium powder are mixed to add in a vacuum induction furnace for smelting at a temperature of 940-1000 DEG C; (2) the mixed powder is cooled, is mixed with zirconium powder, nickel powder and iron powder after crushing, is added in a planet ball mill for mechanical ball milling, and is transferred into a cold pressing mold for pressing; (3) the mixed powder is dispersed and sintered under argon protection at a temperature of 450-500 DEG C; and (4) the mixed powder is crushed to 100 meshes, is added with carbon crystals, boron lithium hydride, nanometer titanium dioxide, ferric oxide, titanium trifluoride and cobalt oxide, and is added in the ball mill for ball milling by 3-5 hours under the hydrogen pressure of 1-2 MPa and the rotating speed of 250-300 r/min to obtain the carbon magnesium base compo
