The current study reports on biosynthesisof pure graphitic carbon nitride (GCN), ZnO nanoparticles (NPs) and ZnO-doped gaphitic nitridenanohybrids (ZnO/GCN-NHs) usingOcimumtenuiflorum(OT)leafextract.GCN synthesis using plant extract was never reported in previous studies. Under direct solar lightphotocatalytic performance of the synthesized GCN, NPs NHs tested degradation methylene orange (MO) dye compared. Among samples, ZnO/GCN-NHsexhibits superior photocatalytic activity, achieving up to 47.56% 150 min MO dye. cytotoxicity biosynthesized NHswas assessed against human dental pulp stem cells these were found be non-toxic, indicating their potential for biomedical applications. antimicrobial properties also well diffusion disc tests four bacterial strains i.e., two Gram-negative Gram-positive. demonstrate significant antibacterial activity with a remarkable inhibition radius Escherichia coli 17.5 ± 1mm, Pseudomonas aeruginosa 15.04 Staphylococcus aureus 27.5 Streptococcus dysgalactiae 25 1 mm. enhanced ZnO/GCN-NHs are hypothesized due increased production reactive oxygen species (ROS) through combination GCN.
