Synthesis and Characterization of NiO Nano-Spheres by Templating on Chitosan as a Green Precursor

摘要: In this study, nickel oxide was prepared through the calcination of extrusion dripped chitosan/nickel nitrate beads. The morphology and structural properties products were studied using various characterization techniques. Uniformly distributed formed as observed from studies surface where processing parameters play a huge role on resulting morphology. TEM results have shown that with crystallite sizes 10–30 nm obtained. Fourier-transform infrared spectra show an intense peak at 525 cm−1, which is attributed to vibration Ni–O bond. Furthermore, XRD NiO diffraction peaks correspond (111), (200), (220), (311), (222) indicates bunsenite structure face-centered cubic phase produced in study. usage 500°C lower limit study justified due complete removal templating material seen thermalgravimetric analysis studies. it obtained largest area synthesized technique 48.024 m2/g pore 19.843 nm. chitosan green template for synthesis nanoparticles has promising allows more economical sustainable approach fabrication nanomaterials.
