▎ 摘　　要

NOVELTY - A graphene-ferric oxide nano particle composite material preparation method involves uniformly mixing the raw materials such as graphite oxide and iron salt in water and separating the mixture. The separated product is washed and heat-treated in air or oxygen to obtain the finished product. USE - Method for preparing a graphene-ferric oxide nano particle composite material. ADVANTAGE - The method enables preparing the graphene-ferric oxide nano particle composite material in a simple and environment-friendly manner and effectively reducing the use of chemical reagent.
