摘　　要：采用模板法和逐层沉积法制备了Fe_3O_4@SiO_2@TiO_2-Ag核壳微米结构,并采用XRD、SEM、TEM、VSM等表征手段对其形貌、组成以及磁学性能进行了表征和分析.光催化测试表明,由于Ag纳米粒子的负载,该核壳结构的光催化性能优异.A novel Fe3O4@SiO2@TiO2-Ag composite was synthesized through template synthesis and layer-bylayer deposition. The obtained samples were characterized in terms of morphology,composition and magnetic property by XRD,SEM,TEM,VSM,etc. The photocatalytic test proved that the well-designed nanocomposite exhibit the significantly superior activity due to the load of Ag nanoparticles.
