| titleOfInvention | Carbon-coated carbon-doped spherical cobalt sulfide and preparation method and application thereof |
| abstract | The invention provides carbon-coated carbon-doped spherical cobalt sulfide and a preparation method and application thereof, and relates to the technical field of preparation of battery catalysts. According to the invention, glucose and ethylene glycol are used as a mixed carbon source, and part of carbon is uniformly doped in the formed cobalt sulfide through hydrothermal reaction and roasting; and a large amount of carbon sources are coated on the outer surface of the cobalt sulfide to form carbon-coated carbon-doped spherical cobalt sulfide. The carbon is coated on the outer surface of the cobalt sulfide and is doped in the cobalt sulfide particles, so that the corrosion of the alkaline electrolyte can be effectively slowed down, and the stability of the catalyst is improved. As can be seen from the examples: the particle size of the spherical cobalt sulfide is 780 nm-1.3 mu m, carbon is doped in the cobalt sulfide particles, a carbon layer is coated on the outer surface layer, and the thickness of the coated carbon layer is 3.1-4.3 nm. |
