Abstract

Background Bimetallic nanoparticles (BNPs) are used in attractive applications in the medicinal, green catalyst, optics, electrochemical and so on. Apart from the catalytic activity, the chemical synthesized BNPs is less energy and environmentally highly toxic. Hence, Au-Ag BNPs prepared by the green synthesis method is suggested to be eco-friendly and have a potential catalytic reduction/degradation activity against environmentally polluted organic dyes. Materials and method In this present work, Ultrasound-Assisted green synthesis of Gold-Silver Bimetallic Nanoparticles (Au-Ag BNPs) was synthesized from Lawsonia inermis seed extract aqueous fraction. The effects of the extract volume, metal ions concentration, pH, and temperature were investigated to determine the optimum conditions of the synthesis of Au-Ag BNPs. Results and discussion UV-vis absorbance of the surface Plasmon resonance centre at 537 nm was confirmed the product of Au-Ag BNPs. FT-IR spectroscopy to determine the phytochemicals groups of the plant extract and Au-Ag BNPs. High-resolution transmission electron microscopy image of Au-Ag BNPs shows polygonal, spherical and irregular shaped with particle sizes 15-35 nm. Under UV-vis the light source, the obtained BNPs had a strong photocatalytic reduction/degradation activity against 4-nitrophenol and methyl orange dye in the presence of NaBH4.
