Attainment of a pristine copper cobaltite (CuCo₂O₄) phase by a fast and easy microwave (MW) assisted method is presented in this paper. The successful synthesis was supported by a series of characterization techniques, which confirmed the presence of a single phase and a possible inverted spinel crystal structure. Furthermore, catalytic performance evaluation of CuCo₂O₄ in propane oxidation demonstrated its selectivity towards carbon dioxide (CO₂) formation, with negligible propanol production. Heating rate modification has a minimal impact on propane conversion, while catalyst stability tests indicate acceptable performance over multiple reaction cycles. X-ray diffraction analysis of the recycled catalyst suggests the formation of CuO, which seems to affect catalytic activity. Although the catalytic trials at lower temperatures resulted in lower efficiency, they effectively suppressed catalyst decomposition and allowed multiple recycling of the catalyst without any loss of catalytic activity.

微波辅助钴酸铜氧化物 （CuCo2O4） 用于丙烷氧化的催化评价


本文介绍了通过快速简便的微波 （MW） 辅助方法获得原始铜钴酸盐 （CuCo2O4） 相的方法。成功的合成得到了一系列表征技术的支持，这些技术证实了单相的存在和可能的倒尖晶石晶体结构。此外，CuCo2O4 在丙烷氧化中的催化性能评估表明其对二氧化碳 （CO2） 形成具有选择性，丙醇的产生可以忽略不计。加热速率修改对丙烷转化率的影响最小，而催化剂稳定性测试表明在多个反应循环中性能可接受。回收催化剂的 X 射线衍射分析表明 CuO 的形成，这似乎会影响催化活性。尽管在较低温度下进行催化试验导致效率较低，但它们有效地抑制了催化剂的分解，并允许催化剂的多次回收，而不会损失任何催化活性。
