| 摘 要： | 为了改善纳米二氧化钛的光催化活性,通过水热法制备了氮钨共掺杂二氧化钛纳米棒。通过扫描电镜(SEM),X射线衍射(XRD),透射电镜(TEM),X射线光电子能谱(XPS)和紫外可见光吸收光谱 (UV-VIS)等对产物进行了相关表征。结果显示：与未掺杂的二氧化钛相比,氮钨共掺杂的二氧化钛纳米棒在可见光区域显示出了较强的光催化活性。因为氮钨阳离子的掺入拓宽了可见光的吸收区域。

| Abstract: | To improve visible light photocatalytic activity of nano-TiO2 particles, Nitrogen and Wolfram codoped TiO2 nanorods were prepared by hydrothermal method. The prepared samples were characterized by SEM, XRD, TEM, XPS and UV-VIS. The results showed that the Nitrogen and Wolfram codoped TiO2 nanorods exhibited a higher photocatalytic activity under visible light irradiation compared with undoped TiO2 because the codoping of Nitrogen and Wolfram ions extended the visible light absorption . |
