Study on catalytic performance of MnOx nanoparticles for CO oxidation

Abstract

As a kind of toxic gas, carbon monoxide is often found in industrial waste gas, automobile exhaust, confined space such as submarines, etc. In recent years, the purification of carbon monoxide has attracted more and more attention. Catalytic oxidation has become a widely used method for carbon monoxide purification. In this paper, manganese oxide nanoparticles were synthesized by emulsion self-assembly method and characterized by X-ray powder diffraction (PXRD) and high-resolution transmission electron microscope (HRTEM). The activity of the oxide nanoparticle catalysts were evaluated on the fixed bed tubular quartz microreactor at atmospheric pressure. The effects of KMnO4 dosage, flow rate and temperature were investigated and the reaction kinetics range was determined.
