Rutile-Phase Sn-Ti Mixed Oxides as Acid Catalysts for the Condensation of C₂-C₃ Oxygenated Compounds in Water.

ABSTRACT: The design of new cost-effective and water-resistant acid catalysts is crucial for valorizing aqueous side-streams to increase the efficiency and competitiveness of bio-refineries in a sustainable way. In this work, Sn-Ti mixed oxides are prepared via a green and scalable co-precipitation method. This synthesis procedure allows obtaining homogeneous rutile-phase Sn-Ti mixed oxides with enhanced textural properties and a higher amount of Lewis acid sites. More importantly, the catalytic behavior of these Sn-Ti mixed oxides is investigated by using an aqueous mixture of C₂-C₃ representative oxygenated compounds, closer to real industrial conditions and differing from usual individual probe molecules studies performed even in the absence of water.
