The impregnation of active carbon with two-component aqueous solutions of Cu and Co nitrates has been investigated and different deposition degrees of copper and cobalt ions have been established. Adsorption analysis has shown modification of the active carbon texture after impregnation with solutions whose concentration of Cu and Co ions exceeds 3%, A catalyst with a high activity in the reduction of NO with CO at 100 degrees C has been obtained. All samples are found to catalyze the complete reduction of NO to N-2. A correlation between the catalytic activity and the Cu:Co ratio in the supported phase has been established,
