The potential of using new mixed metal oxides of the type LnMO3 with Ln = Ce and M = Ni, Cu, and Zn have been prepared by ceramic methods and to find out as a suitable oxidative catalyst . The surface properties (Surface area, Excess surface oxygen and Acidity) of these new mixed oxides of CeNiO3, CeCuO3 & CeZnO3 based on perovskite at different temperatures ( 600,700 and 9000C) have been studied choosing the thermal degradation of urea as a model reaction .From the surface properties measurements it is observed that Surface area and acidity variation goes on decreasing linearly whereas excess surface oxygen ( E.S.O) goes on decreasing exponentially with temperatures. Catalytic activity of CeNiO3 at higher activation temperature (900˚c) is more in comparion to CeZnO3 & CeCuO3. Examination of the X-ray diffraction pattern are used to confirm these new mixed metal oxides of Cerium for its commercial application.
