Powder nanoporous TiO2 with narrow monodisperse pore-size distribution in the range from 2 to 30 nm were prepared by self-assemble micelle system in nonpolar and polar solvents at laboratory temperature and pressure. Nonionic surfactants Triton X-102, 100, 114, 45, 15 were used for preparation of micelle systems. Various approaches were applied for removing of residual organic matter from prepared titania gels: a) calcination, b) improved extraction by supercritical (CO2) and subcritical fluids (H2O, CH3OH) and c) the combination of both forenamed approaches.
