Effect of the Size of Chromium(III) Oxide Crystallites Obtained by Thermolysis of a Carboxylate Complex on Their Catalytic Properties in the Oxidation of CO

摘要

It was established that the activity of catalysts prepared by mechanical mixing of aluminum oxide and the products from thermal decomposition of a carboxylate complex of chromium at 300-700 A degrees C depends non-monotonically on the size of chromium oxide crystallites in the range of 10-50 nm. It was shown that the highest activity is achieved on catalysts in which the size of the chromium oxide crystallites is 23 nm.
