Abstract
Carbon dioxide and carbon monoxide undergo reactive chemisorption with cesium modified Cu(110) and Cu(110)-O surfaces and via the anionic in termediate CO2delta-(a) form a surface carbonate. The CO2delta-(a) spe cies was characterised by VEELS and XPS at low temperature (80 K) and the surface carbonate at 295 K. For cesium modified Cu(110) surfaces c hemisorption of carbon monoxide gives rise to electron energy loss pea ks (nu(CO)) as low as 1450 cm-1 at 295 K.
