| titleOfInvention | Preparation method of nitrogen and sulfur co-doped three-dimensional graphene foam electrode active material |
| abstract | The invention discloses a preparation method of a nitrogen and sulfur co-doped three-dimensional graphene foam electrode material, which comprises the following steps: soaking foamed nickel in dispersion liquid containing graphene oxide, melamine, trithiocyanuric acid and sufficient solvent, and carrying out solvothermal reaction; carrying out heat treatment on the solvothermal reaction product at 500-1200 ℃ under inert atmosphere; and etching the foamed nickel in the heat treatment product through strong acid to obtain the nitrogen-sulfur co-doped three-dimensional graphene foam. The nitrogen and sulfur co-doped three-dimensional graphene foam electrode material prepared based on the method has three-dimensional doped graphene foam and doped nitrogen and sulfur elements; the content of doped nitrogen element is 3-7%, the content of sulfur element is 1-3%, the content of oxygen is 4-12%, and the doping amount is controllable. The experimental method is safe and nontoxic, low in cost and simple and convenient to operate. The prepared doped three-dimensional doped graphene foam electrode can be applied to the fields of lithium ion batteries, supercapacitors, electrocatalysis and the like, and has wide application prospects. |
