Nitrogen oxides (NOx) gases, such as nitrous oxide (N2O), nitrogen oxide (NO), andnitrogen dioxide (NO2), are considered the most hazardous exhausts exhaled by industries andstationary and non-stationary application engines. Investigation of catalytic decomposition of NOhas been carried out on copper ion exchanged with different bases, such as COK12, Nb2O5, Y-zeolite, and ZSM5. The catalytic decomposition of NO is widely accepted as an excellent methodfor the abatement of NO. However, the catalyst that achieves the highest reactivity in terms of NOdecomposition is still a matter of research. The present paper aims to extend the research on thereactivity of non-noble metal-based catalysts using the direct decomposition method to remove NOfrom diesel engine exhaust. The reactivity of catalysts was observed in a quartz fixed bed reactor of10 mm diameter placed in a furnace maintained at a temperature of 200 ◦C to 600 ◦C. The flow of NOwas controlled by a mass flow controller, and the gas chromatography technique was used to observethe reactivity of the catalysts. Analysis showed that adding Cu to COK12, Nb2O5, Y-zeolite, andZSM5 supports resulted in a rise in NO decomposition compared to stand-alone supports. Furtherexperimental trials on the performance of Cu-ZSM5 at varying flow rates of NO showed that the NOdecomposition activity of the catalyst was higher at lower flow rates of NO
