Abstract

Titanium alkoxo oximates with long-chain alkyl groups were used as sol-gel precursors for simultaneous deceleration of the reaction rates of Ti(OR)(4) and creation of porosity upon calcination due to surfactant-like properties. Both titania and hybrid silica-titania films with high surface areas were obtained. Extraction studies showed that only part of the employed oxime is coordinated, but both coordinated and non-coordinated oxim(at)e contribute to pore formation upon heat treatment. Sorption properties of silica-titania hybrid materials were studied by investigating temperature-programmed desorption of toluene.
