摘要：

The oxidation of carbon monoxide by oxygen or nitrogen monoxide on polycrystalline ribbons of platinum, palladium and rhodium under stationary conditions is followed by mass spectroscopy. At temperatures from 250-600°C the ratio of the partial pressures of reactants varies between 0.1 ox/PCO-5 and 10-3 mbar. The rate patterns for platinum and palladium are quite similar. For rhodium the results are more complex. All the results can be interpreted qualitatively by use of the generally accepted elementary reaction sequences for oxidation of carbon monoxide by oxygen, nitrogen monoxide and nitrous oxide on noble metals.
