conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the
在这项研究中,使用可控,有效且简便的微波方法,在环境适宜的条件下构建了Co 3 O 4纳米催化剂。通过SEM,XRD和TEM分析来表征最终的纳米结构。产物具有较小的尺寸分布,均匀的形态和与Co 3 O 4形成相关的晶体结构纳米结构。此外,EDS作图分析证实了最终结构中存在Co和O元素,并通过VSM研究了样品的磁性。此纳米结构中的催化方法中的应用进一步检查,结果表明,它可作为一种新的候选为亚芳基巴比妥和麦德鲁姆的合成, s至由巴比妥和麦德鲁姆醛的Knoevenagel缩合酸, S酸性中水性介质。这些纳米催化剂的高产率将由纳米结构的性质以及本研究开发的实验程序来证明,这影响了产物的理化特性。
