We report on the novel green biosynthesis of Hydrozincite (Zn5(CO3)2(OH)6) from peanut shell water exacted dye and its conversion to Zincite (ZnO). The structural, morphology and thermogravimetric properties of the as synthesized nanopowders were analyzed using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy(FTIR), Raman spectroscopy, Scanning Electron Microscopy (SEM) and TG/DTA thermal analysis. The XRD pattern confirmed the formation of Hydrozincite. The correlations of the results from different techniques confirm the formation of hydrozincite and its conversion to Zincite after heat treatment. The obtained ZnO powders are composed of nanoparticles which are well crystalline with a grain size of 31.11 nm.
