Green synthesis of bimetallic nanocomposite and its applications

Nanotechnology is a rapidly growing field due to the unique physical, chemical, optical and electronic properties of nanomaterials. Bimetallic nanoparticles exhibit enhanced Physiochemical properties through synergistic interactions between two metals making them useful in catalysts,environmental remediation, energy storage, sensing and biomedical applications. Green synthesis method has gained importance as environmentally friendly and economical.

Copper Lithium Oxide (CLO) bimetallic nanocomposite was synthesized via a simple green synthesis method using Lithium chloride and copper acetate as precursors. Guava leaf extract served as the reducing and capping agent, while a few drops of glycerol were added to improve the stability and homogeneity of the synthesized nanoparticles. Lithium chloride, copper acetate and glycerol were added to the guava leaf extract for the formation of the bimetallic nanomaterials. Characterization of the synthesized nanoparticles were carried out using different analytical techniques. UV-Visible Spectroscopy was used to analyze the optical absorption properties and confirm the formation of nanoparticles. XRD analysis was performed to study the crystalline nature and phase formation of the synthesized material. FTIR analysis was carried out to identify the functional groups involved in the synthesis and stabilization of nanoparticles. The CLO nanomaterial is found to be very efficient for complete degradation of methylene blue (MB) and crystal violet, representative textile dye pollutants within short time.

The results obtained from this study demonstrate that green synthesized CLO bimetallic nanoparticles possess promising potential for environmental remediation applications, especially in wastewater treatment through photocatalytic dye degradation. The study highlights the significance of green synthesis as a sustainable and eco-friendly method for the preparation of multifunctional nanomaterials.
