This invention relates to the field of methane catalytic cracking for hydrogen production, and particularly to a glucose-modified activated carbon composite material, its preparation method, and its application. In this invention, activated carbon and glucose are used as the main raw materials, and a glucose-modified activated carbon catalyst is prepared through an impregnation-carbonization process.
