Green Synthesis of Lead Oxide Nanoparticles Using Ocimum Basilicum Extract: Photocatalytic Assessment and Cytotoxicity Effects

In the present study, lead oxide nanoparticles (PbO-NPs) were synthesized through Ocimum basilicum seed extract as a stabilizer agent. The structural and optical features, size, surface area, and morphology of PbO-NPs were evaluated through the usage of FTIR, TGA-DTA, XRD, UV-Vis, EDX, FESEM, TEM, and BET techniques. The thermal behavior of the composition was assessed by the usage of TGA/DTA analysis. The attained results of the XRD pattern show the crystalline structure of PbO-NPs. BET analysis appointed a specific surface area of PbO-NPs. The FESEM and TEM images of PbO-NPs displayed spherical shapes and the diameter of the particles was about 20-30 nm. The toxicity effects of NPs were evaluated on the CT-26 cell line and the IC50 value was about 485.8 mu g/mL. As well as the photocatalytic attributes of PbO-NPs were perused on the degradation of methylene blue (MB) pigment which showed about 90 % degradation after 150 min.
