Surface Science 356 (1-3) : 181-188. ScholarBank@NUS Repository. | Abstract: | The adsorption of N2O on clean, oxygen, deuterium and carbon monoxide modified Ru(001) surfaces was investigated. On the clean surface, three adsorption states have been observed, desorbing at 160-165, 145 and 116-123 K, respectively. On the oxygen modified surface, the presence of oxygen shifts the N2O desorption temperature from 129 K (on a clean surface) to a higher temperature of 173 K (θo = 0.12). The enhanced adsorption of N2O on partially O-covered Ru(004) was also observed. However, on D- and CO-precovered surfaces, the N2O adsorption is destabilized. These results can be accounted for by considering the "through-metal" and the lateral interactions between coadsorbates. | Source Title: | Surface Science | URI: | http://scholarbank.nus.edu.sg/handle/10635/95212 | ISSN: | 00396028 |
