Abstract

The formation and reactivity of an isocyanate complex on a Pd/Al2O3 catalyst was investigated by adsorption measurements and by infrared spectroscopy combined with mass spectrometry. Adsorption studies indicate that the uptake of gases during the coadsorption of NO+CO is significantly larger than the sum of the separately adsorbed gases. The reactivity of surface isocyanate towards H2O, H2, NO and O2 has been studied. The reactivity order at 200°C is H2O≫O2>H2>NO. Mass spectrometric analysis revealed the formation of NH3 in the surface reaction between-NCO and H2O.
