Abstract / Bemerkung
The NO-CO reaction on Pt(100) was examined using temperature programmed reaction methods. The platinum surface was precovered at -80°C with various amounts of both NO and CO and then heated to 370°C. In this case the reaction occurs within a very narrow temperature range around 120°C exhibiting sharp reaction peaks at the mass numbers 28 (N2/CO) and 44 (CO2/N2O). The reaction products were detected by a quadrupole mass analyzer scanning complete mass spectra of 50 amu width at a speed of 15 spectra per second. Thus the course of the reaction was recorded within a single measurement. A subsequent analysis of the data using a modified least-squares fit method was applied to the mass spectra in order to gain information on the true composition of the desorbing gas mixture. To this end isotope and cracking patterns were evaluated. This analysis revealed that beside the major reaction products N2 and CO2 also minor amounts of N2O appear on Pt(100).
