摘要：

The carbonation and hydroxylation state of a series of basic oxides (La2O3, RhLaO3 and YBa2Cu3O7) has been examined by XPS. While hydroxyl groups are characterized by an O(1s) peak at ∼531.4 eV, when carbonate species are present C(1s) and O(1s) peaks at 289.4 and 531.4 eV are recorded, giving an atomic O/C ratio near 3. Heating of samples in UHV up to 973 K leads to removal of most of the carbonate and hydroxyl species, carbonate being much more stable than hydroxyls remaining partially even at the highest temperatures. © 1990.
