<jats:title>Abstract</jats:title><jats:p>We demonstrate a modified sol‐immobilization procedure using (MeOH)<jats:sub>x</jats:sub>/(H<jats:sub>2</jats:sub>O)<jats:sub>1‐x</jats:sub> solvent mixtures to prepare Pd/TiO<jats:sub>2</jats:sub> catalysts that are able to reduce the formation of acid catalyzed products, e. g. ethers, for the hydrogenation of furfural. Transmission electron microscopy found a significant increase in polyvinyl alcohol (PVA) deposition at the metal‐support interface and temperature programmed reduction found a reduced uptake of hydrogen, compared to an established Pd/TiO<jats:sub>2</jats:sub> preparation. We propose that the additional PVA hinders hydrogen spillover onto the TiO<jats:sub>2</jats:sub> support and limits the formation of Brønsted acid sites, required to produce ethers. Elsewhere, the new preparation route was able to successfully anchor colloidal Pd to the TiO<jats:sub>2</jats:sub> surface, without the need for acidification. This work demonstrates the potential for minimizing process steps as well as optimizing catalyst selectivity – both important objectives for sustainable chemistry.</jats:p>
