[Display omitted] •Pristine SrTiO3 and Sr1-xNixTiO3 (x = 0 < x < 0.20) nanoparticles were prepared by hydrothermal method with different Ni concentration.•The structural properties of the nanoparticles were analysed by XRD.•SEM images confirm the morphological changes as the Ni concentration increases.•It was shown that Sr1-xNixTiO3 (x = 0 < x < 0.20) had improved photocatalytic activity for breaking down the antibiotic ciprofloxacin (CFX).•The best photocatalytic degradation performance was obtained from Sr0.91Ni0.09TiO3 nanoparticles. Antibiotics that are present in aquatic environments are causing serious health issues these days. This work utilizes pristine SrTiO3 and Sr1-xNixTiO3 (x = 0 < x < 0.20) nanoparticles which are prepared by hydrothermal synthesis for photocatalytic degradation of antibiotics. In order to confirm the successful development of Sr1-xNixTiO3 (x = 0 < x < 0.20) nanoparticles the structural, morphological, and optical properties were characterized using advanced analytical tools such as the X-Ray Diffractometer (XRD), Field Emission Scanning Electron Microscopy (FESEM), UV–Visible Spectroscopy (UV–Vis), and Photoluminescence (PL). A simple and safe technique was used to synthesize Sr1-xNixTiO3 (x = 0 < x < 0.20) nanoparticles for breaking down the ciprofloxacin (CFX) found in the environment, which was not reported previously. The enhanced photocatalytic activity in Sr1-xNixTiO3 (x = 0 < x < 0.20) for the degradation of antibiotic ciprofloxacin (CFX) was demonstrated. The best photocatalytic degradation performance was obtained from Sr0.91Ni0.09TiO3 nanoparticles. 9 % concentration of Ni − doping shows much higher catalytic activity than other concentrations. These results, suggest that Sr0.91Ni0.09TiO3 nanoparticles can be applied to the aquatic environment to remediate the contaminated antibiotics.
