▎ 摘　　要

NOVELTY - Doping graphene nano chip involves mixing natural graphite and magnetic force steel. The obtained mixture is kept in a sealing container. The obtained sealing container is introduced with nitrogen with pressure 0.2-0.4 megapascal. The obtained product is kept in a magnetic grinding machine. The grinding time is 3-10 hours. USE - Method for doping graphene nano chip (claimed) used for dye-sensitized solar energy battery and electrode. ADVANTAGE - The method enables to dope graphene nano chip in an efficient, cost-effective and eco-friendly manner.
