Abstract
AbstractThree 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.
