Synthesis of copper nanoparticles supported on MoO3 using Sun spurge leaf extract and their catalytic activity

Abstract

Copper nanoparticles supported on MoO3 (Cu NPs/MoO3) were prepared by a green method using Sun spurge leaf extract. Cu NPs/MoO3 nanoparticles were characterized by X-ray diffraction analysis, energy dispersive X-ray analysis, scanning electron microscope and transmission electron microscope. The catalytic activity of this well-defined material in three-component CuAAC reactions was tested to produce 1,4-disubstituted-1,2,3-triazoles in good to excellent yields in water as a green solvent. More importantly, the catalyst can be recovered and reused efficiently up to five consecutive cycles with no significant loss of catalytic activity.
