Abstract The aim of the present study is the synthesis of CuI nanoparticles (CuI Nps) through a green route using red cabbage extract. X-ray diffraction (XRD) analysis confirmed the crystalline nature with face-centered cubic structure of CuI Nps and the average crystallite size was found to be 78nm. The Transmission Electron Microscope (TEM) image revealed the spherical shape of synthesized CuI Nps and the average particle size was around 77.5nm, which is in agreement with the crystallite size calculated from XRD. The presence of capping agent over the metal nanoparticle was confirmed by FTIR spectrum, and the band gap energy was calculated to be 2.75 eV from UV-Vis spectroscopy. The application of green synthesized CuI nanoparticles as a catalyst in Hantzsch reaction to form 1,4-dihydropyridine derivatives, and as an antibacterial agent against Escherichia coli and Staphylococcus aureus bacteria showed, the syntheised CuI to be good catalyst and antibacterial agent.
