Preparation method of cobalt/ferroferric oxide/carbon nanotube/C porous microsphere hydrogen production catalyst

The invention discloses a preparation method of a cobalt/ferroferric oxide/carbon nanotube/C porous microsphere hydrogen production catalyst, and relates to a preparation method of a hydrogen production catalyst. The problem that an existing cobalt transition metal hydrogen preparation catalyst is poor in performance is solved. The preparation method comprises the following steps: preparing sulfonated polyethylene particles and Fe3O4 nanoparticles, then preparing cobalt/Fe3O4 hollow microspheres, adding carbon nanotubes to prepare cobalt/Fe3O4/carbon nanotube composite hollow microspheres by a hydrothermal method, carrying out a deep cross-linking reaction on benzene and benzene methylamine monomers, compounding with the cobalt/Fe3O4/carbon nanotube composite hollow microspheres to prepare a catalyst precursor, and finally plating a cobalt film and carrying out pyrolysis. The hydrogen production catalyst is not easy to agglomerate, large in specific surface area, high in conductivity and high in structural st
