Platinum deposited on monolayer supports in selective hydrogenation of furfural to furfuryl alcohol

Platinum deposited on supports (SiO2, gamma-Al2O3, MgO. TiO2) covered with a transition metal oxide monolayer (TiO2, V2O5, ZrO2) was used in hydrogenation of furfural to furfuryl alcohol. Reactions were carried out under atmospheric pressure and at temperatures from 423 to 573 K. Reduction selectivity from unsaturated aldehyde to unsaturated alcohol (93.8% for Pt/TiO2/SiO2) was higher as compared with the reaction performed over classical platinum metal/metal oxide catalysts (33.8% for Pt/SiO2, respectively). The role of both SMSI and SOOI effects in catalysts activity and selectivity enhancement was demonstrated. (C) 2002 Elsevier Science B.V. All rights reserved.
