Study on active carbon-supported two-component catalysts for NO conversion

The impregnation of active carbon with two-component aqueous solutions of C u and Co nitrates has been investigated and different deposition degrees of copper and cobalt ions have been established. Adsorption analysis has show n modification of the active carbon texture after impregnation with solutio ns 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 suppo rted phase has been established, (C) 1999 Academic Press.
