Abstract
RhSn/SiO2 bimetallic catalysts prepared via an organometallic route ha ve proved to be very active and selective toward several hydrogenation reactions. In this work these catalysts were studied for the dehydrog enation of isobutane to isobutene. It was found that Rh/SiO2 monometal lic catalysts had a null selectivity to isobutene, and this selectivit y increased up to more than 90 % after the addition of tin, using SnBu 4 as precursor.
