Researchers Develop Novel Method for Synthesizing Nickel Nanoparticles Using Plant Extracts

Scientists from the Malaviya National Institute of Technology, Jaipur, have made a groundbreaking discovery in the field of nanotechnology by successfully synthesizing nickel nanoparticles using an extract from the leaves of Azadirachta indica. This novel method could potentially revolutionize the industrial production of metallic nanoparticles, offering a safer and more sustainable alternative to traditional methods. The researchers' findings were published in the Next Nanotechnology journal, a leading publication in the field of nanoscience.

Key Takeaways:

• The study used an extract from Azadirachta indica leaves as a reducing and capping agent to synthesize nickel nanoparticles.
• The optimal conditions for synthesizing stable NiNPs were pH 6.8, temperature 70°C, and 5% leaf extract, with [NiNO3.6H2O] = 1.0 x 10-3 mol dm-3.
• The X-ray diffraction (XRD) analysis revealed a face-centered cubic crystalline structure, and the Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) analyses confirmed a triangular form with particles ranging in size from 7 to 18 nm.
• The study also examined the impact of reactant concentrations, reaction temperature, and solution pH on the nickel nanoparticle fabrication method.
• The findings indicated that the synthesis of NiNPs from A. indica leaf extracts is a safe technology with significant impacts on the industrial synthesis of metallic nanoparticles.
• The research was conducted by Nimish Kumar, Anjali Singh, Vijay Devra, and other researchers from the Department of Chemistry, Malaviya National Institute of Technology, Jaipur.
