▎ 摘　　要

NOVELTY - Preparation of magnetic nano ferroferric oxide graphene compound catalyst comprises ultrasonically dispersing graphite oxide in alcohol and water; separately stirring water-soluble salt of trivalent iron and ferric (II) salt in alcohol; mixing solutions; stirring; heating at 50-90 degrees C; adding ammonia water to adjust pH at 9-11; reacting; magnetically separating product; washing with deionized water; and drying to obtain magnetic nano ferroferric oxide graphene compound catalyst. USE - Preparation of magnetic nano ferroferric oxide graphene compound catalyst. ADVANTAGE - The method is simple and provides magnetic nano ferroferric oxide graphene compound catalyst with uniform size, equal dispersion, better magnetism, good catalytic property, and environment friendly. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a process for preparing magnetic nano ferroferric oxide graphene compound catalyst (Drawing includes non-English language text).
