| titleOfInvention | Preparation method of Fe2O3/CeO2/NiO core-shell structural microspheres |
| abstract | The invention discloses a preparation method of Fe2O3/CeO2/Ni(OH)2 core-shell structural microspheres. The preparation method comprises the following steps of: dissolving ferric chloride hexahydrate, ferric nitrate and polyvinylpyrrolidone (PVP) into deionized water; reacting at a hydrothermal condition to obtain egg-shaped alpha-Fe2O3 microspheres; dispersing the alpha-Fe2O3 microspheres into water again; adding ceric ammonium nitrate, urea and PVP to dissolve; reacting at a certain temperature to coat a CeO2 shell layer; centrifugally washing the obtained product, namely, Fe2O3/CeO2; dispersing into water again; adding nickel sulfate, urea and PVP to dissolve; reacting at a certain temperature to coat an Ni(OH2) shell layer; centrifugally washing the obtained product, namely, Fe2O3/CeO2/Ni(OH)2 after the reaction is done; drying; and transferring into a muff furnace to roast to obtain Fe2O3/CeO2/NiO core-shell structural microspheres. The Fe2O3/CeO2/Ni(OH)2 microspheres and the Fe2O3/CeO2/NiO microspheres, prepared by the preparation method, are of a novel three-layer core-shell structure; the core layers are of a multi-level structure formed by nanometer assembly; and the microspheres can be applied to the development of novel Ni-Ce-Fe based functional materials. |
