Abstract

Chemically resolved in situ imaging of pulses in the system $Rh (110) / NO + H_{2}$ has been achieved with scanning photoelectron microscopy. Based on the experimental results a realistic mathematical model for the excitation of pulses was developed which reproduces the experimental concentration profiles.
