摘要：
The thermal decomposition kinetics of N2H5[Ce(pyrazine-2,3-dicarboxylate)(2)(H2O)] (Ce-P) have been studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), for the first time; TGA analysis reveals an oxidative decomposition process yielding CeO2 as the final product with an activation energy of similar to 160 kJ mol(-1). This complex may be used as a precursor to fine particle cerium oxides due to its low temperature of decomposition.
