Ultra-highly Active Titanium(IV) Oxide Photocatalyst Prepared by Hydrothermal Crystallization from Titanium(IV) Alkoxide in Organic Solvents

Abstract
Microcrystalline titanium(IV) oxide (TiO2) powders having high surface area and high crystallinity were synthesized by high-temperature hydrolysis of titanium(IV) alkoxide in organic media. They were platinized and then used for photocatalytic dehydrogenation of 2-propanol in aqueous solution. The TiO2 catalysts exhibited much higher production rates of hydrogen and acetone than representative active TiO2 catalysts (P-25).
