    Catalytic Activity of CeO2 -NiO for Low Temperature Soot Combustion
    (IJERT, 2014-09-20) Mahofa, Eubert Privilege; Narsaiah, T. Bala; Chakra, Shilpa; Kumar, Pramod; Aftabtalab, Adeleh
    CeO2 (Ce) and CeO2-NiO (CeNi) nano- catalysts were synthesized by co-precipitation from nitrate precursors using 25% ammonia solution (NH4OH) as the precipitating agent. The catalysts were calcined in air at 500ºC and 800ºC for 4h to evaluate the thermal stability. XRD and DLS techniques were used for catalyst characterization. A Thermo gravimetric/Differential Thermal Analyzer (TG/DTA) was used to determine the catalytic activity and soot oxidation reactions. Compared with Ce, Ce-Ni nanocomposite showed lower soot oxidation temperature.
