Thermal Decomposition of Chemisorbed Azomethane on Pd(111)
Abstract
The adsorption and thermal decomposition of azomethane (CH3N=N CH3) on Pd (111) under ultrahigh-vacuum conditions was studied by temperature programmed desorption and work function measurements. Adsorbed azomethane is stable on the surface until N-N bond scission occurs at 250K. Above 280 K, further decomposition forms H(a) and HCN(a) which subsequently desorb at higher temperatures. No C-N bond dissociation is observed on Pd(111). Thus, both N-N and C-H bond cleavages are observed for chemisorbed azomethane on Pd(111), while only C-N bond cleavage is observed in the gas-phase thermal decomposition of azomethane.
