| titleOfInvention | A kind of cobalt particle modified heteroatom doped carbon microsphere and preparation method thereof |
| abstract | The invention discloses cobalt particle-modified heteroatom-doped carbon microspheres, and a preparation method: complexing Co 2+ ions on the surface of Ganoderma lucidum spore powder to obtain cobalt-modified porous carbon microspheres; taking 200 mg of cobalt-modified porous carbon microspheres , add nitrogen source, boron source and/or phosphorus source, grind and mix evenly; in nitrogen atmosphere, keep at 400-1000 ℃ for 1.5~2.5h; oxygen evolution catalyst electrode material, preparation method: modify cobalt particles with heteroatoms Doping carbon microspheres as oxygen evolution reaction catalyst, dispersed in ethanol solution; adding Nafion solution for ultrasonic dispersion, coating the solution on the glassy carbon electrode and drying; the beneficial effect is: by chemically replacing the carbon atoms of the original carbon material with heteroatoms , changing the electronic structure and electrochemical properties of the original carbon material, and further improving the electrochemical performance of the oxygen evolution reaction; in the optimization test, when the current density reaches 10 mA cm ‑2 , the minimum required potential is 1.58 V. |
