Rutile and anatase TiO₂ films were successfully fabricated in TiOSO₄ aqueous solutions containing urea at near room temperature. The molar ratio of urea to Ti (R) in the precursor solutions determined the crystal phase of the TiO₂ films. Rapid precipitation from highly supersaturated solutions was inhibited by complexing Ti⁴⁺ cations with urea, and continuous thin films of rutile and anatase were constructed on substrates. The specific surface area of the films increased from 170 to 360 m²/g with increasing R. The urea affected the specific surface area by selective adsorption on the specific surface of crystallites.
