▎ 摘　　要

NOVELTY - Preparing nano iron oxyhydroxide/metal/graphene ternary composite material comprises ultrasonically dispersing graphite oxide in deionized water to obtain graphite oxide dispersion, then adding dispersed graphite oxide and metal chloride under stirring conditions, and then adding organic solution containing iron pentacarbonyl and reacting in a sealed condition of 50-80 degrees C for 1-3 hours, then filtering, washing, and drying to obtain final product. USE - The nano iron oxyhydroxide/metal/graphene ternary composite material is useful in emulsion catalyzed two-phase organic reactions. ADVANTAGE - The method: has simple process and low cost; and is suitable for industrial production; does not need to add additional reducing agent and stabilizer; and provides nano iron oxyhydroxide/metal/graphene ternary composite material having excellent amphiphilicity, acid and alkali resistance and high-temperature resistance when compared to graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nano iron oxyhydroxide/metal/graphene ternary composite material obtained by above method.
