ADSORPTION AND DECOMPOSITION OF NO ON POTASSIUM PROMOTED Rh(111).

Research output: Contribution to journalConference article

Abstract

The interaction of NO with clean and potassium covered Rh(111) surfaces has been investigated by LEED, Auger electron, electron energy loss (in the electronic range) and thermal desorption spectroscopy in the temperature range between 100 and 1200 K. Adsorption of NO on Rh(111) at 100 K produced three losses at 6. 4, 12 and 15 ev in EEL spectrum. The same losses were found on potassium covered surfaces. From the temperature dependence of these losses and from TD spectra it appeared that the effect of potassium is twofold: it slightly increases the temperature of the existence of NO on the Rh and it promotes the dissociation at higher temperatures.
