The compensation effect in thermal desorption of adsorbate systems with lateral interactions
Surface reactions of nitrogen oxide and ethylene on rhodium(111)
Temperature programming of NO and C2H4 coadsorbed on Rh(111) gives rise to the desorption of a number of gases. Where H2, H20, CO2 and N2 are the main products at low C2H4 coverages, significant amounts of HCN, CO and NO evolve at higher C2H4 coverages. Static SIMS indicates the formation of a large supply of adsorbed CN species, part of which desorbs as HCN, while the remainder decomposes and is responsible for delayed formation of N2. For the highest C2H4 coverages the majority of the initially adsorbed NO desorbs as HCN
