A highlyefficient magnetically separable nano cobalt ferrite catalyst was synthesized via the sol-gel auto combustion method, characterized by powder XRD, SEM, TEM, UV–Visible, FT-IR, magnetic study, and BET isotherm analysis. The synthesized material was found to be an efficient heterogeneous Lewis acid catalyst for the synthesis of 2-aryl benzimidazole derivatives via solvent-free mechanochemical
通过溶胶-凝胶自燃法合成了一种高效的磁性可分离纳米钴铁氧体催化剂,并通过粉末 XRD、SEM、TEM、UV-Visible、FT-IR、磁性研究和 BET 等温线分析进行了表征。发现合成的材料是一种有效的多相路易斯酸催化剂,用于通过无溶剂机械化学合成合成 2-芳基苯并咪唑衍生物。这种新协议的显着特点包括无溶剂反应、成本效益、良好的收率和环境友好性,可在较短的反应时间内提供产品,并且纳米催化剂易于回收和再利用。
