Abstract

Cobalt-copper-zinc ferrite (CoCuZnF) nanoparticles were synthesized using the precipitation method. The characterization of CoCuZnF was carried out using powder XRD, Raman, IR, UV–vis, and FEG-SEM. The TG-DSC data of NTO, and nNTO containing the catalyst was used to study the thermal decomposition behavior. Three non-isothermal methods were used to evaluate the kinetic parameters. The kinetics data suggests that incorporation of CoCuZnF additive can effectively decrease the high activation energy of NTO by ∼83–88 kJ mol−1 and nNTO (∼205–216 kJ mol−1). The decomposition of both NTO and nNTO was faster in the presence of CoCuZnF, suggesting its plausible use in the high explosive munitions containing NTO.

CoCuZnF对3-硝基-2,4-二氢-1,2,4-三唑-5-酮(NTO)和纳米级NTO热分解的催化作用
采用沉淀法合成钴铜锌铁氧体(CoCuZnF)纳米颗粒。采用粉末XRD、Raman、IR、UV-vis、fg - sem对CoCuZnF进行表征。利用NTO和含催化剂的NTO的TG-DSC数据研究了其热分解行为。采用三种非等温方法对其动力学参数进行了评价。动力学数据表明,CoCuZnF添加剂的掺入可以有效降低NTO的高活化能(~ 83 ~ 88 kJ mol−1)和NTO (~ 205 ~ 216 kJ mol−1)。CoCuZnF存在时,NTO和NTO的分解速度都更快,这表明CoCuZnF可能用于含有NTO的高爆弹药。
