摘要 以二水乙酸锌为锌源、氢氧化钠为沉淀剂和钠源,采用溶液沉淀法和煅烧处理合成了具有可见光活性的Na掺杂ZnO光催化剂。采用X射线衍射仪、扫描电子显微镜及紫外-可见漫反射光谱仪对合成的催化剂样品进行表征。结果表明,Na掺杂ZnO光催化剂的带隙为3.1eV,具有可见光吸收活性,添加聚乙二醇合成的催化剂样品经550℃煅烧后表现出较高的活性,在光照时间70min内对亚甲基蓝的降解率达到了96%。

Abstract: Sodium-doped zinc oxide photocatalysts with visible-light activity were synthesized by a precipitation method and subsequent calcination process using zinc acetate dihydrate as the source of zinc,and sodium hydroxide as the precipitant and the source of sodium.The synthesized samples were characterized by X-ray diffraction,scanning electron microscopy and UV-Vis diffuse reflectance.The results indicated that the sodium-doped zinc oxide with a band gap of 3.1eV had visible light activity,and that the product synthesized with polyethylene glycol additive and subsequently calcined at 550℃ showed a higher photocatalytic activity and the degradation rate of 96% for methylene blue with 70min.
Key words:  precipitation method    zinc oxide    visible light absorption    photocatalysis
