• The catalytic oxidation of carbon monoxide on zirconium dioxide was kinetically examined in order to compare with the results of titanium dioxide. The experiment was carried out under gas pressures of 10<SUP>−2</SUP>−100 mmHg at 400–550°C. The reaction rate was proportional to <I>P</I><SUB>CO</SUB> and did not depend upon <I>P</I><SUB>O<SUB>2</SUB></SUB>, and there was no retarding effect by carbon dioxide. The rate constant of this oxidation reaction almost agreed with that of the reduction of zirconium dioxide by carbon monoxide. The reaction mechanism could be explained in the same manner as that on titanium dioxide. The catalytic activity of zirconium dioxide for this reaction was almost the same as that of rutile. The activation energy was about 12.5 kcal/mol, and this value was intermediate between those of anatase and rutile. The same relation was obtained in the activation energies of the thermal desorption of surface oxygen from these catalysts.
