The invention discloses a methane reforming catalyst for the production of hydrogen and a preparation method thereof, which more particularly relates to a Ni methane vapor reforming catalyst for the production of hydrogen which takes a nanometer cerium zirconium composite oxide as the carrier and the corresponding preparation method, and belongs to the methane reforming catalyst field. The catalyst comprises 5-30 wt% of active Ni, 0-10 wt% of noble metal catalytic promoter, 0-10 wt% of rare earth and/or the catalytic promoter of alkaline earth oxide, 50-95 wt% of nanometer cerium zirconium composite oxide carrier with the particle diameter of 5-20 nm. The invention is characterized by simple preparation method, high reactivity, strong anti carbon performance, good stability, low cost, etc.; when the invention is applied to the methane vapor reforming catalyst for producing hydrogen, the requirements of industrialization on catalyst reactivity and usage life can be satisfied. The invention can be largely applied in fuel cell-hydrogen area.
