| Özet |
| Previous work has shown thatCO2 adsorption on bulk potassium leads to the formation of oxalate ions below room temperature. These C2O4 groups decompose in vacuo to carbonates, CO3, and CO around 300 K and the carbonates further to oxides and carbondioxide above 700 K. The present work addresses reaction routes by calculations of adsorption coordinates in combination with spectroscopic data from time-resolved in situ infrared spectroscopyand analyses of desorbing species. Oxalate intermediates are formed by reactions between surface CO2-ions and adsorbed neutral molecules. Weakly adsorbed CO2 alone cannot follow this route. The energetics of oxalate formation is compared with CO2 adsorption on clean and oxidized potassium. Rearrangements between almost isoenergetic oxalates are discussed in connection with reaction routes and branching ratios. CO is released from one oxalate … |
