| 摘 要： | 采用机械诱导固相反应法制备了硫掺杂锡酸锶;通过热重分析、X射线粉末衍射(XRD)、紫外可见漫反射(UV-Vis DRS)、紫外可见分光光度计(UV-Vis)、X射线光电子谱(XPS)等对所合成的样品进行表征并以罗丹明B为目标降解物,考察了硫掺杂锡酸锶在模拟可见光照射下的催化活性.结果表明:合成产物的吸收边由紫外区域红移到了可见光区,有效地提高了其在可见光下降解罗丹明B的光催化活性.

| Abstract: | The sulfur doped SrSnO3 was prepared by mechanically induced solid-state reaction and characterized by TG-DTA,XRD,DRS and XPS.The photocatalysis activity of sulfur doped SrSnO3 for the degradation of rhodamine B in aqueous under the visible-light irradiation was also investigated.The results show that the absorption edge region of the sulfur doped SrSnO3 red-shifted from ultraviolet to visible region,which effectively improves the photocatalysis activity of S doped SrSnO3 for the degradation of rhodamine B ... |
