%X tio2 nanoparticles with attractive physicochemical properties have synthesized by means of the sol-gel method and acid hydrolysis. the obtained nanoparticles have characterized by the xrd-rietveld refinement, bet and tem techniques, and tested in the photodecomposition of acetaldehyde. the degree of decomposition of acetaldehyde by the sol-gel tio2 nanoparticles was directly proportional to the brookite mass fraction but inversely proportional to the anatase mass fraction and crystallite size.
