【摘要】 以Zn(NO3)2,ZrOCl2和NaOH为主要原料,采用共沉淀-水热法制备了晶型规整的掺Zr纳米ZnO复合紫外屏蔽材料。研究了Zr的掺杂量、水热温度、水热时间和Zr的掺杂方式等对材料紫外屏蔽性能的影响,得到了制备掺Zr纳米ZnO紫外屏蔽材料较好的制备条件为:共沉淀掺杂,Zr掺杂量为3.5%,水热温度150℃,水热时间0.5 h。采用X射线衍射仪和透射电镜对样品进行了表征,结果表明,样品晶型好、尺寸均匀。更多还原

【Abstract】 Zr doped zinc oxide composite UV- shielding material with regular crystal form was prepared by hydrothermal co- precipitation method with zinc nitrate,zirconium oxychloride and sodium hydroxide as starting materials.Effects of dosage of Zr doping material,temperature and time for hydrothermal treatment and method for Zr doping on the UV- shielding performance of the product were investigated.The optimum preparation conditions were identified as:dosage of doped Zr,3.5%;temperature and time of hydrothermal treatment,150 ℃ and 0.5 h respectively.The final product was characterized by X- ray diffraction(XRD) and transmission electron microscope(TEM).Results showed that the product displays good crystal form and uniform size.更多还原
