摘要: Abstract The adsorption of CO on silica-, alumina- and titania-supported Pd catalysts (2, 5, 10 wt% Pd) has been studied by microcalorimetry temperature programmed desorption (TPD) experiments in a flow system at atmospheric pressure. On supported catalysts, bridge-bonded was found to be the dominant CO(ads) species. observed influence loading energetics explained terms particle size and/or surface structure crystallites. Support materials can divided into active (TiO 2 , Al O 3 ) inert (SiO supports, where with supports are characterized (1) an increased sensitivity reduction temperature, (2) promotion dissociation, (3) activity carbon towards hydrogenation, as compared silica.
