Green synthesis and characterization of silver and copper bimetallic

In materials science, green synthesis has gained extensive attention as a reliable, sustainable, and eco-friendly protocol for synthesizing a variety of materials and nanomaterials, such as metal/metal oxide nanoparticles, hybrid materials, and bioinspired materials. As such, green synthesis is regarded as an important tool to reduce the destructive effects associated with the traditional methods of synthesis for nanoparticles commonly utilized in laboratory and industry. They are environmentally friendly because the toxic chemicals produced during the biosynthesis of the nanoparticles can be degraded with the help of enzymes present in the microbes. In this study, we compiled the basic procedures and workings of green synthesis methods, particularly as they relate to the bimetallic synthesis of Ag and Cu nanoparticles utilizing natural extracts. FT-IR, XRD, PSA, FL, and TGA were used to characterize the synthesized Ag-Cu nanoparticles. In addition, silver nanoparticles were used as a potential photocatalyst for the effective degradation of Rhodamine dye under UV light illumination, achieving an efficiency of roughly 84 % after 180 minutes. The antibacterial activity was tested on B. subtilis, E. coli, Staphylococcus, Enterobacter and Pseudomonas. Physicochemical properties increased the antibacterial activity of Cu/Ag NPs by causing a homogenous distribution and reducing oxidation and agglomeration. The work's findings demonstrate the advantages of employing a geometrical substrate to increase the antibacterial activity of bimetallic nanoparticles (NPs). This could potentially lower the need for pure Cu/Ag salts in NP-based antibacterial applications.
