TiO2 nanoparticles were synthesized by thermal decomposition of a precipitate obtained from a precursor solution of titanium isopropoxide (IV) and isopropyl alcohol. The as-prepared precipitate was heated at various temperatures and the obtained samples were morphologically, texturally and structurally characterized using TGA?DTA, gas adsorption, SEM, XRD and FTIR. The UV?vis radiation absorption and the photocatalytic activity also were verified. The TiO2 sample heated at 300 °C shows the best results to be applied as blocker in solar skin protector.
