▎ 摘　　要

NOVELTY - An iron oxide/manganese dioxide/reduced graphene oxide material preparing method involves providing iron oxide and potassium permanganate as precursors and hydro-thermal synthesis grading porous iron oxide/manganese dioxide. Iron oxide/manganese dioxide graphene water solution is taken and stirred with iron oxide/manganese dioxide/reduced graphene oxide compound by adding reduction agent to obtain iron oxide/manganese dioxide/reduced graphene oxide material. USE - Method for preparing iron oxide/manganese dioxide/reduced graphene oxide material. ADVANTAGE - The method enables simplifying process, preparing material with high stability and high purity and increasing production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an iron oxide/manganese dioxide/reduced graphene oxide material.
