Conversion of Alcohols on Stoichiometric and Reduced Rutile TiO2 (110): Point Defects Meet Bifunctionality in Oxide (Photo-)Chemistry

Abstract Oxidic (photo-)catalysts have the potential to play an important role efficiently implement sustainable feedstocks and green energy sources into future technologies. They may be used not only for solar harvesting, but also hydrogen production or being essential fabrication of fine chemicals. Therefore, it is crucial develop a detailed understanding how atomistic environment catalyst can designed in order promote distinct reaction pathways influence final product distribution chemical reactions. In this perspective article, we survey surface (photo-)chemistry methanol on rutile TiO 2 surfaces hybrid catalysts based thereon. Especially bifunctionality by Lewis acidic basic sites combined with strong impact point defects such as reduced titanium (mainly Ti 3+ interstitials) shall illuminated. It shown selective activation either O–H, C–H C–O bonds molecule tune overall conversion, switch between oxidative reductive routes favor deoxygenation, partial oxidation C–C coupling latter ones are particular interest introduce from biomass feedstock already existing petrochemical Graphical
