▎ 摘 要
NOVELTY - Reduction of graphene oxide involves pretreating graphene oxide in strongly acidic suspension containing sulfuric acid after Hummers process, and subjecting reaction by-products and unreacted reagents, e.g. manganese ions with varying degrees of oxidation, to reduction with phosphoric acid (I) or its salts such as hypophosphates containing cations forming soluble salts with sulfate anions (VI). USE - Reduction of graphene oxide.
