Sr-doped CuO nano photocatalyst has been synthesized by low cost and eco-friendly electrochemical method. The chemical composition, morphology, size, and optical properties were studied by EDAX, XRD, SEM, FT-IR and UV-Vis, PL spectroscopy, XPS and BET analysis. The XRD study revealed that synthesized Sr-doped CuO has a crystallite size of 35.2 nm with a monoclinic structure. The synthesized nanoparticles have a bandgap of 3.1 eV. The photodegradation of methylene blue dye under sunlight indicates that 0.06 g Sr-doped CuO acts as effective catalyst. The antibacterial susceptibility of Sr-doped CuO nanoparticles was evaluated by disc diffusion Kirby-Bauer method using human pathogens Bacillus subtilis (MTCC 121) , Pseudomonas aeruginosa (MTCC 183), Salmonella typhi (MTCC 733) showed good bacterial inactivation. The photo-voltaic studies revealed that Sr-doped CuO exhibits lower activity compared to nano ZnO and higher activity compared to commercial ZnO. Sr-doped CuO nanoparticles scavenges . OH and protects methylene blue from further fading which is confirmed by free radical scavenging activity studies.(c) 2022 Published by Elsevier B.V.
