In this work NiMn2O4, NiMn2O4/TiO2 and NiMn2O4/CeO2 nanocomposites were prepared by co-precipitation method and evaluated for the selective catalytic reduction of NOx with NH3. Various characterization methods such as X-ray diffraction, field emission scanning electron microscope, specific surface area, average pore diameter, temperature programmed desorption (NH3-TPD), temperature-programmed reduction (H2-TPR) and inductively coupled plasma optical emission spectrometer were conducted to probe the physical and chemical properties of these catalysts. The catalytic activity tests showed that in the temperature window of 200–400 °C and the space velocity of 10,000–40,000 h−1, NiMn2O4/CeO2 demonstrated the best performance among the synthesized catalysts.
