Abstract
Adsorption-desorption kinetics of carbon monoxide on Ru(0001) and Ru(21̄1̄22) single crystal surfaces was investigated by measuring the absolute adsorption rate and the absolute desorption rate while the adsorption was actually proceeding. The absolute adsorption rate was a non-linear function of the surface coverage of CO and showed similar behavior on both two surfaces. The absolute desorption rate included a term depending on the gas-phase pressure, likewise our previous works on Pd and Rh. This pressure-dependent part of the desorption rate increased with the temperature of the crystals with activation energies of 4.9 kcal mol −1 for Ru(0001) and 6.1 kcal mol −1 for Ru(21̄1̄22).
