Porous polycrystalline cobaltosic oxide film loaded noble metal monatomic catalyst, preparation method and application thereof in seawater electrolysis
The invention belongs to the technical field of seawater electrolysis, and discloses a porous and polycrystalline cobaltosic oxide film loaded precious metal monatomic catalyst, a preparation method and application of the porous and polycrystalline cobaltosic oxide film loaded precious metal monatomic catalyst to seawater electrolysis, and the porous and polycrystalline cobaltosic oxide film loaded precious metal monatomic catalyst has the structural characteristics of being ultrathin, porous and spliced by multiple crystal faces. Precious metal single atoms are adsorbed on the porous and polycrystalline cobaltosic oxide film to adjust an active site electronic structure and a bimetallic site synergistic effect, and the porous and polycrystalline cobaltosic oxide film loaded with different precious metal single atom catalysts can be obtained by adjusting different precious metal salt solutions. The preparation method is simple, convenient to operate and high in repeatability; the polycrystalline cobaltosic oxide film wraps and loads precious metal single atoms, and the distribution is uniform; the composite material is prepared into slurry, and the slurry is coated on carbon cloth to be used as an anode for seawater electrolysis hydrogen production, so that the composite material has an excellent energy catalysis application prospect..
