Abstract:

TiO₂ nanopowders were synthesized by non-hydrolytic sol−gel synthesis and solvothermal method. Effects of the type of alcohol on the properties of TiO₂ nanopowders were investigated. XRD and FSEM were used to characterize TiO₂ nanopowders. The results showed that TiO₂ nanopowders with diameters of about 50nm and micro-spheres with diameters of about 400~500nm were obtained by non-hydrolytic sol−gel synthesis, when ethanol and isopropanol were used as oxygen donor and solvent, respectively. TiO₂ prepared with ethanol by non-hydrolytic sol−gel synthesis and calcined at 700°C consisted only 3.8% rutile phase. After solvothermal synthesis, TiO₂ nanopowders with diameters of about 50nm were obtained when ethanol and isopropanol were used as the oxygen donor. However, submicrometer spheres with uniform size distribution were obtained with 1-octanol.
