Modelska, Magdalena; Binczarski, Michal J.; Kaminski, Zbigniew; Karski, Stanislaw; Kolesinska, Beata; Mierczynski, Pawel; Severino, Courtney J.; Stanishevsky, Andrei; Witonska, Izabela A. published the artcile< Bimetallic Pd-Au/SiO2 catalysts for reduction of furfural in water>, Application In Synthesis of 97-99-4, the main research area is palladium gold silicon dioxide furfural water bimetallic catalyst reduction.
Catalytic systems based on bimetallic Pd-Au particles deposited on SiO2 were prepared by ultrasonically assisted water impregnation and used in the hydrogenation of furfural obtained by the acidic hydrolysis of waste biomass (brewery’s spent grain) in aqueous phase. Pd-Au/SiO2 catalysts containing 50 g of Pd and 2-100 g of Au per 1 kg of catalyst were characterized by high activity in the studied process and, depending on the Pd/Au ratio, selectivity to 2-methyloxolan-2-ol. The modification of 5%Pd/SiO2 by Au leads to the formation of dispersed Au-Pd solid solution phases, which was confirmed by XRD, XPS, ToF-SIMS, SEM-EDS, and H2-TPR techniques. The effect of dilution of surface palladium by gold atoms is probably crucial for modification of the reaction mechanism and formation of 2-methyloxolan-2-ol as the main product.
