Abstract:
Catalytic conversion of NO and CO over Cu substituted cobalt oxide spinels show excellent activity for CO-O2 and NO-CO reactions. Lower concentration of Cu in cobalt oxide spinel is having an enhancing effect on the catalytic conversion. Best activity among the tested catalyst was found for Co sub(2.9)Cu sub(0.1)O sub(4) and complete conversion (100 percent) is observed at 93 degrees C for CO oxidation by O2 and 209 degrees C for NO reduction by CO. Prepared catalysts show promising activity compared to few of the precious metal based catalysts reported in the literature. The influence of moisture and oxygen on catalytic conversion has been studied.
