摘要：

The adsorptional behaviour of CO2 has been studied on a stepped (332) Cu surface at an adsorption temperature of 95 K. TDS experiments show that CO2 is chemisorbed on this Cu surface. Most of the CO2 dissociates and CO can be found in the TDS. The oxygen produced by the surface reaction does not desorb from the surface and can be detected by AES after TDS experiments. The oxygen stabilizes some CO2 thus a CO2 desorption state with considerable higher desorption energy develops as a function Of CO2 exposure. The different adsorption species have been identified spectroscopically, utilizing He Il induced UPS.
