| 内容記述 | CO_2 gas was employed to characterize the surface of alkali metal-modified MgO by IR spectroscopy. Doses of alkali metals changed the composition of CO_2-derived species because of the enchanced basicity of the surfaces. Li showed the highest modification effect of the three alkali metals used ； this result was in the reverse order of electron-donating ability. Taking inso account the fact that Li^+ can be substituted for Mg^^<2+> due to their similar sizes，and that alkali metal oxide and hydroxide were shown by XRD patterns， the existence of an Li site strongly-connected with oxygen was considered. The data from both lR spectra and TPD profiles leads to the possibility of quantitative evaluation of basicity of the surface only by IR spectroscopy to a certain degree. | |||||
