Perovskites can absorb solar energy and are extensively used in various catalytic photocatalytic reactions. However, noble metal particles may enhance the catalytic, photocatalytic, antibacterial activities. This study demonstrates cost-effective green synthesis of photocatalyst perovskite LaMnO3 its modification with Ag nanoparticles. The nanocomposite was achieved through a hydrothermal method employing aqueous extract derived from Citrus limon (L.) Burm peels. properties fabricated perovskites LaMnO3-Ag nanocomposites were evaluated characterized by Ultraviolet-Visible spectroscopy (UV-Vis), Diffuse Reflectance Spectroscopy (DRS), X-ray diffraction (XRD), Fourier-Transform Infrared (FT-IR), High-Resolution Transmission Electron Microscopy (HRTEM), Scanning (SEM), Energy-Dispersive (EDX) Brunauer–Emmett–Teller (BET) surface area techniques. particle size distribution % observed to be 20 60 nm after using TEM images. maximum percentage 37 for 43 LaMnO3-Ag. In addition, utilized as degradation Rose Bengal (RB) dye activities against Staphylococcus aureus (S. aureus) Escherichia coli (E. coli). band gap nanoparticles calculated 12.642 m2/g 3.44 eV, respectively. presence hydrothermal-bio reduction significantly impacted crystallinity. BET found 16.209 m2/g, at 2.94 eV. shows enhanced effectiveness RB (20 PPM) (92%, R2 = 0.995) pseudo-first-order chemical kinetics (rate constant, k 0.05057 min−1) within 50 min due ultimate combination bio-reduction technique. activity optimized different reaction times, doses (0.2, 0.4, 0.6, 0.8 g/L), concentrations (20, 30, 40, ppm). synthesized explored based on colony-forming unit (cfu) images bacterial nanoparticle interactions S. E. coli. An amount µg/mL sufficient work highest both bacteria. process is economically environmentally friendly. Additionally, it has wide range effective exclusive applications remediating pollutants.
