A facile and efficient method for fabrication of magnetic composite microspheres CoFe2O4@TiO2@Au is demonstrated. The shells of anatase TiO2 were coated onto a magnetic CoFe2O4 core via liquid-phase deposition procedure, and then Au nanoparticles were deposited onto CoFe2O4@TiO2 microspheres through seed-mediated growth. XRD, TEM, and VSM were used to investigate the structure, morphology and magnetic...
