The catalyst is used for the decontaminstion of nitrogenoxides in the presence of a reducer in room temperature. Thereducer is carbon oxide which is cheap and accessible and nonitrogen oxide (N2O3) is produced when using it. The catalystworks in the presence of oxygen. It contains copper and manganesein the form of amorphous oxides with specific atom content ofcopper and manganese, the manganese oxides have the generalformula MnOx.1 claim
