Abstract:
Three different morphologies of CeO2 supports (nanoparticle, nanocube, and nanorod) were prepared by hydrothermal technique and further Mn2O3 metal was impregnated on CeO2 supports using wet-impregnation methods, and their activity for NO reduction using NH3−SCR technique was analysed. The synthesized catalysts and supports were further characterized through scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET). The catalytic performance of Mn2O3/CeO2-nanoparticle has shown the highest conversion (76 %) compared to the other two catalysts in the temperature range of 50–450 °C.
