摘要: Pt-Sn/MgO catalysts prepared by Surface Organometallic Chemistry were investigated 119 Sn Mossbauer spectroscopy. The results indicate that, on the reduced catalyst, most of tin forms bimetallic particles with a Sn-rich surface, whereas remainder is present as Sn(II) and Sn(IV) compounds. Changes structure after catalytic test implications properties in selective hydrogenation unsaturated aldehydes to alcohols are discussed.
