▎ 摘　　要

NOVELTY - Preparing graphene-iron oxide composite material comprises (i) adding graphene oxide into mixed solution of deionized water and ethanolamine and ultrasonically dispersing, (ii) dissolving polyethylene glycol-10000, ammonium ferrous sulfate and hexamethylenetetramine in mixed solution, (iii) placing mixed solution in a sealed environment and incubating at 180-200 degrees C for 15-20 hours, and (iv) washing reaction and drying to obtain final product. USE - The method is useful for preparing graphene-iron oxide composite material (claimed). ADVANTAGE - The material has excellent photocatalytic degradation activity under ultraviolet light irradiation, excellent stability and ferromagnetic behavior.
