An overview of kinetic and spectroscopic investigations on three-way catalysts: mechanistic aspects of the COÂ +Â NO and COÂ +Â N2O reactions

Spectroscopic and kinetic investigations of the following reactions lead to a better understanding of the functioning mode of three-way catalysts at molecular scale, in order to improve their selectivity beahaviour towards the production of nitrogen.(1)2NO + 2CO → N2 + CO2(2)2NO + CO → N2O + CO2(3)N2O + CO → N2 + CO2
