摘要：

High resolution FTIR spectroscopy was used to study the adsorption of CO at 300 and 78 K on unsintered and sintered monoclinic ZrO2, and the relevant data suggest that the latter material exposes prevalently two extended and structurally ordered crystal planes, as well as relatively few terminations characterized by structurally defective and highly energetic sites. HRTEM micrographs confirm that, upon sintering, larger crystallites with sharper borders are produced, in which the (111) and (001) crystal planes are by far predominant.
