Preadsorbed carbon monoxide on alumina-supported palladium can be used as an indicator to examine the rearrangement of the metallic surface upon the action of hydrogen. The changes of the ir spectra from CO and Pd/Al/sub 2/O/sub 3/ when the sample is brought into contact with hydrogen show that the Pd(111) plane is formed on disordered palladium crystallites even at room temperature, probably as a result of the formation of palladium hydride. Depending on the experimental conditions a number of ir bands are observed when a mixture of CO and H/sub 2/ is passed over the catalyst. These bands are believed to belong to intermediates of carbon monoxide hydrogenation. It is suggested that the surface species is formed on palladium and after that is strongly adsorbed on alumina due to the spillover phenomenon. An attempt is made to explain the difference between the reaction pathways of methanation and methanol formation.
