【摘要】 以工业级纯钛箔为模板,硝酸钐为钐物种掺杂给体,采用阳极氧化法制备钐掺杂的TiO2光催化剂,用SEM、XRD对制备的样品进行表征,以甲基橙为模拟污染物,考察了钐掺杂的TiO2光催化剂的光催化活性。结果表明:制备的光催化剂为锐钛矿相和少量金红石相的混晶;硝酸钐掺杂浓度为0.001 mol/L,其光催化性能最好,且光催化重复使用性能良好。更多还原

【Abstract】 The photocatalyst of samarium doped TiO2 was prepared by anode oxidation method using industrial grade titanium foils as templates and samarium nitrate as the doped spicy.The morphology of the as-prepared samples was observed by SEM and XRD.The photocatalytic activity of Sm-doped TiO2 was carried out using methyl orange as the pollutant.The resulted showed that the prepared photocatalysts were mixed crystals of anatase phase and a small amount of rutile phase.It was also confirmed that the catalyst had high catalytic activity and stability when the concentration of samarium nitrate was 0.001 mol/L.更多还原
