| Abstract: | The anatase TiO2 nanopowders were prepared by simple sol-gel method. The as-prepared products were analyzed by XRD, SEM and TEM. The formation process of anatase TiO2 was also analyzed by TG--DTA. The photocatalysis property of as-prepared powders was measured and the results showed that photocatalysis degradation rate of rhodamine B could reach 98% in presence of TiO2 nanopoders. |
