| titleOfInvention | Preparation method of 3D carbon nanosphere oxygen reduction catalyst HFeSSC |
| abstract | A preparation method of a 3D carbon nanosphere oxygen reduction catalyst HFeSSC comprises the steps of preparing zinc sulfide and glutathione into a solution, dropwise adding ethylenediamine to adjust the pH value of the solution, adding the solution into a reaction kettle, and preparing zinc sulfide nanoparticles with controllable sizes through high-temperature hydrothermal method; dispersing zinc sulfide into deionized water, adding ferric chloride and dopamine hydrochloride monomer into the solution, fully mixing, adding trihydroxymethyl aminomethane to adjust the pH value, and carrying out in-situ polymerization to obtain a purple black solid; and carrying out high-temperature carbonization and acid washing to obtain the porous iron-based nitrogen and sulfur co-doped carbon HFeSNC electrocatalyst. The catalyst prepared by the invention has a 3D porous structure, a high specific surface area and high conductivity, contains a novel FeNxSy active site, and has the advantages of high activity and high stability in the oxygen reduction reaction process due to the advantages of stable pore channel structure of the material and the like. |
