▎ 摘　　要

NOVELTY - Reducing graphene oxide by using extracellular polymer involves inoculating target strain into culture medium, separating and purifying to obtain extracellular polymer EPS, adding extracellular polymer EPS to graphene oxide suspension, adjusting pH of mixture to be acidic, reacting under light, separating and purifying to obtain reduced graphene oxide. USE - Method for reducing graphene oxide by using extracellular polymer. ADVANTAGE - The method enables to reduce graphene oxide by using extracellular polymer that is easy to be industrialized, high graphene oxide reduction degree, low cost and satisfies reaction condition.
