摘      要：Ceria nano discs were synthesized by the stepwise thermal decomposition strategy of the oxalate precursor. A series of Ce（1-x）CuxO2（x = 0, 0.02, 0.1, 0.2 and 0.3） nano sized oxide systems were prepared through thermal decomposition route. Kinetic characterization of formation of solid solution was made by isoconversional strategy under non-isothermal condition. Introduction of various reactant molar ratios of Cu2＋：Ce4＋ has a pivotal role in the creation of new oxygen vacancies, decomposition strategy,particle size and shape. Cu2＋ doping（x = 0.02 and 0.1） damages the disc shaped morphology of *** distribution of Cu2＋ on the oxalate precursor has a significant role in the catalyzing activity for the destruction of oxalate bond to oxide. 2 mol% doped Cu2＋ promotes breaking of oxalate bonds in nitrogen atmosphere. In vitro cell viability assay illustrates enhanced toxicity to cancer cells with 10 mol% Cu2＋ doped ceria.
