Abstract

The nanosized titania modification η-TiO2 has been obtained from titanyl sulfate with different starting precursor concentration, under different hydrolysis and coagulation conditions. Characteristics of samples (nanoparticle and crystallite size, specific surface, pore volume) have been determined by scanning electron microscopy, small-angle and wide-angle X-ray diffraction, and nitrogen physical adsorption at −196°C, and their correlation with the synthesis conditions has been established. Optimal technological regimes ensuring fabrication of samples with a high yield of η-TiO2 modification and specified functional characteristics have been found.
