Reactions of nitrogen oxides (NO, N2O) with the surface of a copper-chromium oxide catalyst

Complete detoxification reaction by NO reduction with CO over nano‐sized copper‐substituted Cr2O3

“…Cu incorporation in Cr 2 O 3 has enhanced catalytic activity in Cr 1.96 Cu 0.04 O 3 . This resulted from copper that enhances the adsorption property in Cr 2 O 3 making catalyst active at lower temperature . A significant increase in the NOCO reaction was seen when Cr 2 O 3 was doped with small amount of copper.…”

“…N 2 O formation was observed because of the surface reduction by NO. At high temperature NO reacts on the surface giving N 2 O and O (ads) on surface . From the reaction it was observed that NO conversion occurs prior to CO oxidation, may be due to transformation of NO to N 2 O to N 2 and oxidation of CO using surface oxygen.…”
