The invention discloses a method for preparing magnetic porous material, in which a nmagnetic, modified hydrophobic NiFe204 and hydrophilic TiO2 are used as stabilizers, nNiFe204 is prepared by solvent thermal method, TiO2 is prepared by sol-gel method, then nW/O/W multiple Pickering emulsion is prepared by sol-gel method; and a composite magnetic ncatalyst TiO2/PS/NiFe24 is prepared by multiple Pickering emulsion polymerization. The ninner and outer layer of colloidal particles are fixed by polystyrene in this invention; the inner nlayer NiFe204 serves as a magnetic medium, and the outer layer TiO2 acts as a catalyst; the nTiO2 is coated in the outer layer, which greatly reduces the influence of polystyrene on its ncatalytic performance. Polystyrene is widely used in optical and chemical instrument parts, ntransparent film and capacitor dielectric layer because of its excellent electrical properties, high nfrequency characteristics and radiation resistance.n-1/3nA magnetic, modified hydrophobic NiFe204 and hydrophilic TiO 2 are used nas stabilizers, NiFe204 is prepared by solvent thermal method, TiO 2 is nprepared by sol-gel method, then W/O/W multiple Pickering emulsion is nprepared by sol-gel method. n4102 nPreparation of TiO 2/PS/ NiFe204 composite magnetic catalyst by multiple nPickering emulsion polymerization nFigure 1 |
