Abstract: Amorphous titanium dioxide (TiO₂) nanoparticles were obtained by the sol–gel method with subsequent crystallization to anatase by annealing at 350 °C for 4 h. Based on the research results using XANES and EXAFS X-ray absorption spectroscopy, it was determined that the as-prepared amorphous TiO₂ contains vacancies in the oxygen and titanium sublattices.

Keywords: EXAFS, XANES, XAS, titanium dioxide, anatase, nanoparticles, sol–gel synthesis.
