采用一种简单的方法制备了铁掺杂氧化锌的粉末,将其作为光催化剂对甲基橙(MO)的光催化降解进行了研究。通过X射线衍射图谱(XRD)、紫外可见吸收光谱(UV-vis)、扫描电子显微镜(SEM)对所合成样品进行了表征。结果表明,采用铁掺杂氧化锌光催化剂,甲基橙的光催化降解显示出比纯氧化锌催化剂更高的光催化降解率,这被归因于铁的掺杂使颗粒的表面性质改变,有效的阻止了团聚,改善了紫外可见光的吸收。铁掺杂氧化锌光催化剂是甲基橙光催化降解过程的一种有潜力的光催化剂。
An iron-doped zinc oxide powder was prepared by a simple method and studied as a photocatalyst for the photocatalytic degradation of methyl orange (MO). The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis and scanning electron microscopy (SEM). The results showed that photocatalytic degradation of methyl orange with iron-doped zinc oxide photocatalyst showed a higher photocatalytic degradation rate than pure zinc oxide catalyst due to the change of the surface properties of the particles due to the doping of iron, Effectively prevent the reunion, improve the absorption of UV-visible light. Iron-doped zinc oxide photocatalyst is a potential photocatalyst for the photocatalytic degradation of methyl orange.
