Nanosized titanium dioxide (TiO 2 ) is synthesized by laser-induced pyrolysis using titanium isopropoxide as a liquid precursor. The specific surface area of as-produced nanopowders measured by the Brunauer-Emmett-Teller method (BET) varies from 84 to 110 m 2 g −1 . X-ray diffraction (XRD) and Raman scattering showed that the TiO 2 nanocrystals had an anatase structure. The grain size of the nanoparticles was estimated from scanning electron microscopy, XRD and BET measurements. The reflectiondoi:10.1088/0022-3727/38/9/014 fatcat:ygzynk7tzjcbxhczvhkwbk3ti4
