Abstract
Adsorption, decomposition and oxidation of benzene on Ir(1 1 1) was studied by high resolution (synchrotron) XPS, temperature programmed desorption and low energy electron diffraction. Molecular adsorption of benzene on Ir(1 1 1) is observed between 170 K and 350 K. Above this temperature both desorption and decomposition of benzene take place. An ordered adsorbate structure was observed upon adsorption around 335 K. Decomposition involves C–C bond breaking as the formation of CHad is observed. The presence of a saturated Oad layer (0.5 ML) weakens molecular benzene adsorption and suppresses decomposition.
