中文摘要:
      以钦酸四丁醋为原料,采用溶胶一凝胶法、水热沉淀法、水解法制备了纳米二氧化钦粉经XRD对三种方法制得粉体进行了表征,讨论了三种方法的优缺点。以水解法制得二氧化钦粉对六种染料进行了脱色研究,结果表明其有良好的光催化脱色性能。
英文摘要:
      Nanosized titanium dioxide powder was prepared via Sol- Gel methods 、Hydro thermal methods、Hydrolysis methods from tetrabutyl titanate . As-prepared powders were charaterized by XRD technique. The advantage and disadvantage of the three met hods were studied. The decoloration of the six dye was studied in titanium dioxide which was prepared by hydrol ysis met hods. The results showed the decoloration rate of the six dyes was good.
