The invention discloses a carbon-based isomerization catalyst modified Mg-Ni-Ce hydrolysis hydrogen production material and a preparation method thereof.The hydrolysis hydrogen production material comprises zero-dimensional carbon quantum dots (SP), one-dimensional carbon nanotubes (CNTs), two-dimensional graphite powder (GP) and a modified Mg-Ni-Ce hydrolysis hydrogen production material, namely, an M-xN (M = Mg-Ni-Ce, N = SP, CNT and GP) composite material, the percentage content x of carbon-based isomerization catalysts (SP, CNT and GP) is 0-30 wt.%, and the percentage content y of the carbon-based isomerization catalysts (SP, CNT and GP) is 0-30 wt.%. And the balance of Mg-Ni-Ce alloy. According to the method, the problems that an MgO passivation layer on the surface of the magnesium-based alloy and a colloid Mg (OH) 2 film formed in the hydrolysis hydrogen production process wrap unhydrolyzed metal particles, the hydrolysis initial rate is reduced, medium transmission is hindered, the hydrolysis hydrogen
