In this study, cobalt titanate nanoparticles (CoTiO₃ NPs) were synthesized and applied as a photocatalyst to degrade atrazine. Scanning electron microscopic (SEM) analysis showed irregularly shaped particles prone agglomeration, while X-ray diffraction (XRD) confirmed the formation of rhombohedral CoTiO₃ phase with crystallite size 3.76 nm. Raman spectroscopic vibrations typical for Ti–O Co–O bonds well-defined structure. Thermogravimetric (TGA) that remained stable up 800 °C. The photocatalytic activity NPs was tested under sunlight irradiation results obtained demonstrated excellent efficiency compared photolysis reaction. influenced by concentration (20–50 ppm), catalyst dosage (0.5–2.0 mg/L), pH (4.21–10.22), time (0–120 min). exhibited surface area 32.5 m2/g (DFT) 828.03 m⁻1 (BET), pore volume 0.03925 m3/g, bandgap energy 2.66 eV.

The green synthesis of zinc oxide (ZnO) nanomaterials is increasingly recognised in due to their minimal toxicity, high biocompatibility, and simple fabrication methods. This study presents the eco-friendly ZnO nanoparticles (ZnONPs) using Lilium lancifolium floral extract as a bio-reductant. Comprehensive physicochemical characterisation, including spectroscopic microscopic analyses, was conducted elucidate nanoparticles' structural morphological properties. ZnONPs displayed spherical hexagonal morphologies, consisting 49.34% oxygen 50.66% zinc. Zeta potential measurements indicated negative surface charge, BET disclosed specific area 35 m2/g, an average pore size ~ 25 nm, volume 0.74 cm3/g. Dynamic light scattering (DLS) revealed particle 27 nm polydispersity index (PDI) 0.332. antioxidant capacity ZnONPs, assessed through DPPH radical scavenging assays, showed activity ranging from 39.2% 71.2%, with IC50 47.2 µg/mL. performance surpassed (72.3 µg/mL) comparable ascorbic acid (IC50 = 37.4 µg/mL). Photocatalytic degradation studies on methyl violet (MV), Rhodamine B (RhB), reactive blue 19 (RBBR) dyes followed pseudo-first-order kinetics adhered Langmuir-Hinshelwood adsorption models. Additionally, lipid peroxidation inhibition assays demonstrated both preventing peroxidation, indicating promising antimicrobial properties for combating bacterial infections.
