The thermal stability of CH3NCO adsorbed on Cu{110} and Pt{110} is investigated using HREELS, TPD, and ARUPS. CH3NCO desorbs largely without fragmentation from Cu{110}, but on Pt{110} only about 20% of the adsorbed CH3NCO desorbs intact, with 80% decomposing on the surface at T > 200 K into CO(a), H(a), CHx(a), N(a) and NHy(a) fragments. The kinetics of the surface decomposition were characterised for 220 < T < 300 K by HREELS and the activation energy for CH3NCO decomposition was found to vary strongly as a function of coverage.
