Photocatalytic Conversion of Tertiary Alcohols on Rutile Titania — •Carla Courtois, Moritz Eder, Kordula Schnabl, Constantin Walenta, Martin Tschurl, and Ueli Heiz — Chair of Physical Chemistry, Department of Chemistry & Catalysis Research Center, Technische Universität München, Lichtenbergstr. 4, 85748 Garching, Germany

While tertiary alcohols are usually inert towards oxidation, photocatalysis of tertiary alcohols on a bare single crystal rutile titania show new and unexpected reaction pathways. Tertiary alcohols are selectively photo-oxidized on titania at room temperature by a C-C bond cleavage leading to a ketone and the respective alkane. Studies under highly defined vacuum conditions allow elucidating the reaction mechanism and the impact of adding a metal co-catalyst on the product spectrum.
