Green Synthesis of Bimetallic Nanoparticles and its Catalytic Activity of Multicomponent Reactions and Antibacterial Activity

Abstract

AbstractThis present research work focuses on synthesizing Ag−Cu bimetallic nanoparticles utilizing an aqueous extract leaf of Excoecaria agallocha, employing a green synthesis route. The incorporation of silver (Ag) with copper (Cu) induces synergistic effects that enhance reaction kinetics and reduce the multicomponent reaction time. The catalysts synthesized through this environmentally friendly approach were thoroughly characterized using various analytical techniques, including HR‐TEM, XRD, SEM‐EDX, UV‐Vis Spectrophotometry, and FT‐IR. The UV‐visible spectrum displayed a peak at 257 nm, while the FT‐IR spectrum exhibited peaks at 574 cm−1, indicative of bimetallic peak reductions attributed to the influence of plant metabolites. HR‐TEM and XRD revealed the crystalline with (111), (200), (111), (200), and (220) plane values and shapes of BMNPs. Furthermore, the Ag−Cu bimetallic nanoparticles demonstrated outstanding catalytic performance with high product yield, along with notable reusability and recyclability and excellent antimicrobial activity when compared with commercial antibacterial chloramphenicol.
