The structure and activity of charcoal supported palladium catalysts Part II. Hydrides phase formation and activity of palladium charcoal catalysts in benzene hydrogenation

Some dependence has been found in turn over number for benzene hydrogenation over various Pd/Charcoal catalysts for metal particles below 40 Ǻ in sizes, approximately. In order to account for the above results attention was paid for their association with β Pd-H hydride appearance during the catalytic process, as detected in situ by X-ray diffraction analysis.
