▎ 摘 要
NOVELTY - Preparing iron (II,III) oxide/graphene composites comprises (i) mixing the oxidized graphene emulsion with iron(III) oxide-hydroxide sol, and separating the solid-liquid to obtain iron(III) oxide-hydroxide/oxidized graphene composites, (ii) adding iron(III) oxide-hydroxide/oxidized graphene composites under the protection of the inert gas, and heating at 200-500?OC for 1-5 hours. USE - The method useful for Preparing iron (II,III) oxide/graphene composites(claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the iron (II,III) oxide/graphene composites obtained by above method.
