▎ 摘  要

NOVELTY - Industrial production for preparing preparing sulfur-nitrogen-containing few-layer graphene by using animal hair comprises putting animal hair in diluted hydrochloric acid, rinsing overnight, drying, crushing and sieving, mixing and grinding the graphene powder and crushed animal hair to obtain graphene-animal hair blend; putting the graphene-animal hair blend in a muffle furnace, firstly introducing nitrogen, heating at 450-600 degrees C, keeping the temperature for 12-24 hours, and slowly reducing to room temperature to obtain primary product containing sulfur-nitrogen-containing few-layer graphene; and taking the primary product containing sulfur-nitrogen-containing few-layer graphene, washing by diluted hydrochloric acid, washing by ethanol, washing with deionized water until the water washing liquid is neutral, and vacuum drying. USE - The method is for industrial production for preparing sulfur-nitrogen-containing few-layer graphene by using animal hair. ADVANTAGE - The method has simple separation and simple technique, is easy to control, can realize industrial production, and provides product with high yield and excellent performance.
