Abstract

The aim of this research is to find a nano-catalyst supported by MWNT with high conversion and selectivity on NOx abatement. At first, the MWNT was oxidized by an acidic method and characterized by XRD, TEM, TGA, ASAP, and FTIR methods. Then the 12wt% MnOx over MWNT and Oxidized-MWNT were prepared by an incipient wetness impregnation technique. Comparing the result of 12wt% MnOx with MWNT/Oxidized-MWNT catalysts showed that introducing the OXYGENATED SURFACE GROUPS over the surface of the MWNT increased conversion and selectivity at 200 °C from 60 to 97 and 87 to 100%, respectively. ASAP and TEM analysis proved that the oxygenated groups improved dispersion of the active phase over the support by increasing the support surface area. Also, H2-TPR results showed increased reducibility of the catalyst by increasing availability of MnOx as the active phase through the oxygenated groups over Oxidized-MWNT.
