| 摘 要： | 用共沉淀法制备了SrTiO3光催化剂及Fe3O4/SrTiO3复合光催化剂.通过紫外-可见漫反射光谱、XRD、SEM-EDX对其进行表征,以甲基橙为探针分子考察其光催化性能.结果表明,适量Fe3O4的掺入可明显提高Sr-TiO3光催化剂对可见光的吸收,从而增强其光催化性能;在光降解甲基橙的反应中,掺杂10%Fe3O4的SrTiO3光催化剂其催化活性是纯SrTiO3光催化剂的两倍.

| Abstract: | SrTiO3 photocatalyst and Fe3O4/SrTiO3 composite photocatalyst were prepared by using co-deposition method.The samples were characterized by means of UV-vis diffuse reflectance spectrometry,XRD,and SEM-EDX.Photocatalytic activity was evaluated with photodegradation of methyl orange.The results indicate that Fe3O4 doping increased visible light absorption of SrTiO3 photocatalyst obviously,which enhanced photocatalytic performance of SrTiO3 photocatalyst.The photocatalytic activity of the 10% Fe3O4 doped SrTiO3 photocatalyst is three times as much as that of pure SrTiO3 photocatalyst in terms of the photodegradation of methyl orange. |
