MOLECULAR BEAM STUDIES ON OXIDATION OF CO ON Pd WITH DIFFERENT MIXED RATIOS OF P_(CO) TO P_(O2) ~*

摘要

Here some steady-state experiments on oxidation of CO on Pd were performed on a molecular beam apparatus. It is found that the characteristics of the rate of CO2 formation r versus substrate temperature T are dependent on the ratio P=PCO/PO2 in the mixed beam. These characteristics are related to the complicated interactions of co-adsorbed CO and O particles on Pd surface.
