Selective Catalytic Reduction of Nitric Oxide with Fe-Mn-Ce Metal Oxide-Based Catalysts

Abstract:

Article Preview

Nanosized cerium-manganese ferrite particles were prepared by co-precipitation approach. The structural evolutions and morphological characteristics of the nanopowder were investigated using X-ray diffractometry, transmission electron microscopy and thermo-gravimetry. XRD results showed that particles with crystallite size in nanometer scale were formed. TEM studies showed the morphology of the prepared cerium-manganese ferrite with a crystallite diameter of 20 nm at the calcination temperature of 500°C for 4 h. The catalyst showed high activities for SCR of nitric oxide with ammonia.
