Abstract
Titanium dioxide (TiO 2) nanopowders were successfully prepared by thermal processing of the precursor of titanium hydroxide, urea and sodium acid carbonate (NaHCO 3). The products were characterized by X-ray diffractometry, scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The results show that NaHCO 3 has a certain effect on the average crystallite size and dispersity of TiO 2 nanopowders, at the same time other phases (Na 2SO 4 and Na 2CO 3) will be introduced. However, Na 2SO 4 has distinctive intercalation ability and catalytic activity. TiO 2 (anatase) powders can be prepared at −600 °C for 2 h with addition of 2–10 wt% NaHCO 3, and the average crystallite size is 20.0–22.3 nm. The surface of the sample mainly consists of Ti, O, C, Na and S five species elements.
