Abstract

A solid phase reaction between Co(NO 3) 2·6H 2O and Al 2O 3 is used to obtain CoAl 2O 4 whose activity in the complete oxidation of CO and stability with respect to the catalytic poison SO 2 are investigated. The activation energy of oxidation in the absence of SO 2 and in its presence after a 6 h reaction is determined. It is established that CoAl 2O 4 is stable towards SO 2 and its catalytic activity in the oxidation of CO is commensurable with the activity of a platinum catalyst.
