The present study describes synthesis of copper oxide nanoclusters by electrochemical reduction method wherein copper metal sheet was used as a sacrificial anode while platinum was used as an inert cathode. The electrolysis was carried out at varied current density for 2 hrs in aqueous solutions using tetrabutyl phosphonium bromide (TBPB) as a capping agent. The nanostructure of the synthesized nanoclusters have been analyzed using X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectrometer (FT-IR) and UV–Vis spectro-photometer. The copper oxide nanoclusters were screened for their antimicrobial activity.
