Preparation and Characteristics of Nanometer Anatase TiO2 Powder by Sol-gel Method |
| |
| Abstract: | Nanometer anatase TiO2 powder was prepared by sol gel method, combination of microemulsion technique and co boiling distillation. The powder was characterized by TEM and XRD. Results showed that particles calcined at 650 ℃ for 2?h were anatase TiO2, with content of anatase in 99%, sizes in 30～50?nm, and no agglomeration. |
