Abstract
Adsorption and thermal reaction of NO on Pt(111) at temperatures from 25 K to 80 K have been studied by means of infrared reflection absorption spectroscopy. The physisorbed NO molecules from (NO)2 species on the chemisorbed NO at low temperatures. There are at least two kinds of (NO)2 species. The dimer species are decomposed into NO, which immediately desorbs above ∼40 K. The remaining predominant species after 80 K heating is on-top linear NO species.
