The surface conductivity changes of 2 at.% and 2 at.% have been measured during Au/MnO x , MnO x Pt/SnO 2 cyclical exposures to CO and dry air at 130 รC. At each stage of the gas exposures, the corresponding surface compositions were determined using x-ray photoelectron spectroscopy (XPS) and ion sc
