研究用热分解法从 CdCO3前驱体制备 CdO 纳米颗粒的非等温动力学。采用 Malek 模型模拟法和改进的非模型等转化率 Vyazovkin 法对所得 DSC 和 TDA 数据进行分析。结果表明，从 CdCO3制备 CdO 纳米颗粒的反应属于自动催化反应。Sestak?Berggren 模型能很好地描述该反应过程。另外，计算得到 CdCO3热分解反应的表观活化能为(119.19±9.97) kJ/mol，并建立了该热分解反应的反应速率方程。
The non-isothermal kinetics of CdO nanoparticles prepared from CdCO3 precursor using thermal decomposition method was investigated. A model-fitting Malek approach and a model-free advanced isoconversional method of Vyazovkin were applied to the analysis of the DSC and TGA data. The results showed that CdO nanoparticles prepared from CdCO3 followed an autocatalytic reaction. Sestak–Berggren model could favorably describe the studied reaction process. Moreover, the apparent activation energy of CdCO3 decomposition was calculated to be (119.19±9.97) kJ/mol and the explicit rate equation form of CdCO3 decomposition was established.
