The decomposition of nitric oxide (NO) was studied over carbon nanotubes (CNTs) supported Cu-Mn catalyst. CNTs were home-made by cracking of methane over the LaNiO3 catalyst. At the temperature of 500°C, 71.8% NO was decomposed into N2 (71% selectivity) with the by-products of NO 2 and N2O (29% selectivity in total). X-ray photoelectron spectroscopy investigation found the existence of Mn3+ and Cu + in Cu-Mn/CNTs, respectively. The NO temperature programmed desorption (NO-TPD) study indicated that the adsorption of NO resulted in the desorption of NO, NO2, N2O, N2, O2, and CO2. The apparent activation energy for NO decomposition over Cu-Mn/CNTs is 23 kcal/mol. Copyright © 2014 Taylor & Francis Group, LLC.
