The present work describes the excellent catalytic activity of copper(II) oxide nanoparticles (NPs) towards N-arylation of aniline and imidazole at room temperature. The copper(II)oxide NPs were synthesized by a thermal refluxing technique and characterized by FT-IR spectroscopy; powder XRD, SEM, EDX, TEM, TGA, XPS, BET surface area analysis, and particle size analysis. The size of the NPs was found
目前的工作描述了氧化铜 (II) 纳米粒子 (NPs) 在室温下对苯胺和咪唑的 N-芳基化的优异催化活性。氧化铜(II)纳米粒子是通过热回流技术合成的,并通过红外光谱表征;粉末 XRD、SEM、EDX、TEM、TGA、XPS、BET 表面积分析和粒度分析。发现纳米颗粒的尺寸约为 12 nm,表面积为 164.180 m2 g-1。该催化系统还被发现是可回收的,可以在后续催化运行中重复使用,而不会显着降低活性。
