โœฆ Synopsis

Infrared spectra of NO and NO, adsorbed on MgO, Al,O,, NiO and ZrO, have been studied. The results obtained indicate that some NO2 dissociates on the catalysts. The adsorption of NO as well as NO, leads to the formation of the nitrosonium ion (NO+) and coordinated NO species on the surface of the oxides. Additionally, the adsorption of NO2 produces coordinated nitrates whereas NO gives rise mainly to surface nitro groups.

We present the results of the in situ infrared study of the behavior of NO with CO on Pt(100) carried out in a continuous ร‘ow reactor at 470 K and 500 K. The frequency of the solitary IR band observed at 470 K during adsorption of nitric oxide shifted by 68-73 cm-1 when we used 15N18O instead of NO.

The effect of NO and SO 2 on the oxidation of a CO-H 2 mixture was studied in a jet-stirred reactor at atmospheric pressure and for various equivalence ratios (0.1, 1, and 2) and initial concentrations of NO and SO 2 (0-5000 ppm). The experiments were performed at fixed residence time and variable t
