A novel, green and cost-effective heterogeneous nanocatalyst was synthesized by supporting copper (I) oxide nanoparticles on magnetic agar (Cu₂O/Agar@Fe₃O₄). Then, it was characterized with multiple techniques, such as scanning electron microscopy and transmission electron microscopy images, energy-dispersive X-ray analysis, Fourier-transform infrared (FT–IR) spectroscopy, thermogravimetric (TG) analysis, X-ray diffraction pattern, vibrating sample magnetometer curve, and inductively coupled plasma analysis. The catalytic activity of the newly designed catalyst was investigated in a one-pot three-component reaction of alkyl halides, sodium azide, and alkynes to obtain 1,4–disubstituted 1,2,3–triazoles in high yields in water–ethanol media. The present catalyst was simply separated from the reaction media by an external magnet and reused at least five subsequent runs without significant activity loss.

通过在磁性琼脂（Cu ₂ O / Agar @ Fe ₃ O ₄上负载氧化铜（I）纳米颗粒）合成了一种新颖的，绿色且具成本效益的非均相纳米催化剂。）。然后，用扫描电子显微镜和透射电子显微镜图像，能量色散X射线分析，傅立叶变换红外（FT-IR）光谱，热重（TG）分析，X射线衍射图谱等多种技术对其进行表征。 ，振动样品磁力计曲线和电感耦合等离子体分析。在烷基-卤化物，叠氮化钠和炔烃的一锅三组分反应中研究了新设计催化剂的催化活性，从而在水-乙醇介质中以高收率获得了1,4-二取代的1,2,3-三唑。通过外部磁体将本发明的催化剂简单地从反应介质中分离出来，并在不显着降低活性的情况下重复使用至少五次。
