| 摘 要： | 采用沉淀法合成了立方晶型Sb2O3纳米晶,通过X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)、紫外-可见漫反射光谱(UV-Vis DRS)和电子自旋共振谱(ESR)等对样品进行了详细的表征。以紫外光光催化降解甲基橙为反应模型评价了样品的光催化性能。结果表明:沉淀法合成的立方晶型Sb2O3纳米晶颗粒小,表现出良好的光催化性能。对立方晶型Sb2O3纳米晶光催化降解甲基橙的原因进行了探讨,并提出了降解甲基橙的反应机理。

| Abstract: | Cubic Sb2O3 nanocrystalline was obtained via a precipitation method. The sample was characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (DRS) and electron spin resonance (ESR), etc. The photocatalytic degradation of methyl orange under UV irradiation as a model reaction was used to evaluate the photocatalytic properties of the material. The results revealed that Sb2O3 nanocrystalline prepared by the precipitation method exhibited small particle size and high photocatalytic activity. Factors affecting the photocatalytic activity of the as-prepared Sb2O3 nanocrystalline are discussed, and a possible mechanism of the photocatalytic degradation of methyl orange over the cubic Sb2O3 nanocrystalline is also proposed. |
