A facile method for honey mediated bio-synthesis of nickel nanoparticles and its characterisation

In the present research, a statistical model was designed for optimizing three process variables for manufacturing nickel nanoparticles (NiNPs) using honey as bio-supported reducing agent. Characterisation of nanoparticles was performed using UV-vis spectrophotometer, nanoparticle size analysis was conducted by laser diffraction method and transmission electron microscopy (TEM) was used for morphological studies. Fourier transform infrared spectroscopy (FTIR) analysis was done for identifying the chemical nature of the capping agent deposited on the nanoparticle and energy dispersive x-ray (EDX) analysis was carried out for element determination. XRD analysis was used for the crystallographic determination. Characterisation by all the methods pointed to the crystalline nature of the NiNPs with a mean diameter of 31 nm.
