NOVELTY - Preparing patterned nitrogen-sulfur co-doped graphene aerogel, comprises (1) ultrasonically dispersing graphene oxide into water to obtain graphene oxide dispersion; (2) adding thiamine hydrochloride or rhodamine to graphene oxide dispersion, ultrasonically processing until completely dissolved, pouring ultrasonic dispersion into container, and placing in vacuum freeze drying device for freezing and drying for 24 hours to obtain formed solid mixture; and (3) placing the solid mixture in a high temperature tubular furnace, sealing and introducing nitrogen, raising the temperature of the tubular furnace to 600-800℃ according to the heating speed of 5℃/minutes, and keeping for 0.5-2 hours, and slowly cooling to room temperature to obtain patterned nitrogen-sulfur co-doped graphene aerogel. USE - The method is useful for preparing patterned nitrogen-sulfur co-doped graphene aerogel. ADVANTAGE - The method realizes the nitrogen, doping sulfur atoms, further partially recovers the structure of graphene, and realizes the fast synthesis of nitrogen-sulfur co-doped graphene under the condition of non-metal catalyst. The product has high purity, large specific surface area, and excellent adsorption performance.
