Abstract
Static secondary ion mass spectrometry (SSIMS) was applied in either real-time or temperature programmed (TPSSIMS) mode in order to probe the dissociation kinetics of NO on Rh{110}. The validity of the experimental approach was ensured by detailed calibration measurements using temperature programmed desorption (TPD), ion scattering spectroscopy (ISS) and monochromatized X-ray photoelectron spectroscopy (MXPS). The TPSSIMS data were evaluated to obtain both the activation energy, E dis = 15 ± 2 kJ mol , and the pre-exponential, v dis = 10(1.9±0.5) s −1, assuming first order kinetics in a Polanyi-Wig
