▎ 摘　　要

NOVELTY - Chemical reduction of nitrogen-sulfur-cobalt doped graphene involves mixing graphite oxide and deionized water to obtain dispersed liquid, boiling traditional Chinese medicine in deionized water, cooling, filtering, centrifuging to obtain supernatant liquid, mixing dispersed liquid and supernatant liquid, refluxing, cooling to room temperature, washing and drying. USE - Method for reducing nitrogen-sulfur-cobalt doped graphene (claimed) used in supercapacitor, sensor, catalysis, dye battery and lithium-air battery. ADVANTAGE - The method is environmental-friendly, low cost, simple, and has mild reaction condition.
