▎ 摘 要
NOVELTY - Preparation of ionic liquid-based binary doped graphene involves adding ionic liquid, carbon tetrachloride and potassium metal to reactor under inert gas atmosphere, and heat-treating at 160-240 degrees C for 10 minutes to 12 hours. USE - Preparation of ionic liquid-based binary doped graphene used in fuel cell and metal-air battery. ADVANTAGE - The method enables preparation of ionic liquid-based binary doped graphene having excellent electrical properties, with high yield, by simple process.
