Betel leaves mediated green synthesis of nickel nanoparticles: Synthesis and characterization

Abstract

Bio-nanotechnology offers biosynthetic, environment friendly pathways for the preparation of nanomaterials. In this work, nickel nanoparticles (NiNPs) are synthesized by using betel leaves as reducing agent. Reduction to NiNPs was confirmed by UV-VIS analysis. The effect of independent variables, i.e. temperature and strength of reducing agent on absorbance of the reaction mixture and process optimization was done using RSM as per central composite design (CCD). The chemical group present on the deposited nanoparticles was identified using FT-IR. Particle size estimation was done on TEM and nanoparticle size analyser. The crystallinity of the nanospheres formed was established using XRD. Nano metal formation was confirmed using EDX.
