Pristine and Nickel doped Copper Oxide (CuO) Nanocomposite were synthesized using Centratherum Punctatum leaf extract. The structural characterization is performed employing XRD, SEM, and EDAX. Pure Copper Oxide nanoparticles (CuO Nps) exhibit leaf-like morphology, but Nickel-doped Copper Oxide nanocomposites exhibit a mixture of rod, spherical and hexagonal morphology. Owing to the XRD data, the resulting particles for NiO NPs, CuO NPs, and Ni-doped CuO nanocomposite comprised crystallite sizes of 35 nm, 41 nm, and 37 nm, respectively. The optical properties and functional group of the materials are analyzed utilizing UV-Vis and FTIR. The rise in the measured optical band gap values was seen by the blue shift noted in the UV-vis study subsequent to nickel doping. The existence of different functional groups in samples is verified by FT-IR characterization. The electrochemical analysis is studied by cyclic voltammetry. It exhibits an elevated specific capacitance value of 314 ????????−1 for Ni doped copper oxide nanocomposite. The antibacterial activity studies reveal that the Ni-doped nanocomposite is active against gram-negative bacteria over and above the gram-positive bacteria species.
