In this study, silver nanoparticles (AgNPs) were synthesized using a green method involving Peltophorum pterocarpum flower extract. Successful formation of AgNPs was confirmed by a characteristic surface plasmon resonance peak at 416 nm in the UV-Vis spectrum. SEM and TEM analyses revealed uniformly spheroidal nanoparticles with an average size of 25.77 nm, while EDX confirmed the presence of silver. SAED patterns showed bright spots, indicating a polycrystalline nature, which was further supported by XRD, revealing a crystallite size of 15.58 nm and a lattice parameter of 0.4007 nm. FTIR spectra identified hydroxyl and carboxyl groups as key agents in nanoparticle reduction and stabilization. DLS analysis reported a hydrodynamic diameter of 99.41 nm and a PDI of 0.326, suggesting good monodispersity. The nanoparticles exhibited good stability with a zeta potential of - 14.7 mV. Catalytic studies showed rapid degradation of Acid Blue 113 dye in the presence of NaBH<sub>4</sub>, achieving a rate constant of 0.247 min<sup>-1</sup> at 30 mg/L. These results demonstrate the environmental remediation potential of biogenically synthesized AgNPs and underscore the benefits of sustainable green synthesis approaches for industrial wastewater treatment.
