(Cu‐Cu2O@RGO) was prepared through a one‐pot reflux synthesis method. The morphology, crystal structure and composition of the prepared Cu‐Cu2O@RGO were characterized using transmission electron microscopy, X‐ray diffraction, and X‐ray photoelectron, infrared and Raman spectroscopies. Cu‐Cu2O@RGO as a heterogeneous catalyst was applied to tandem reactions of halides and sodium azide with terminal alkynes
还原氧化石墨烯(RGO)负载的Cu–Cu 2 O纳米复合材料(Cu‐Cu 2 O @ RGO)是通过单锅回流合成方法制备的。使用透射电子显微镜,X射线衍射,X射线光电子,红外和拉曼光谱学对制备的Cu‐Cu 2 O @ RGO的形态,晶体结构和组成进行了表征。Cu-Cu 2 O @ RGO作为非均相催化剂被用于卤化物和叠氮化钠与末端炔烃的串联反应,以有效合成1,4-二取代的1,2,3-三唑。而且,该催化剂显示出极好的可回收性,几乎没有金属的浸出。与均相催化剂相比,Cu‐Cu 2O @ RGO是一种绿色高效的催化剂,在串联方法合成1,2,3-三唑化合物时可回收,易于分离且高度稳定。
