An eco friendly and solvent free method for the synthesis of Zinc oxide nano particles using glycerol as organic dispersant

Zinc oxide nano particles can be synthesized using a simple solvent free, economic and eco friendly combustion method. The structural characterization of synthesized nano particles are carried out using XRD and SEM. The optical characterization was carried out using UV and Photoluminescence spectrofluorimeter. The XRD result shows that the nano particles are of hexagonal shape and the average crystal size of the Zinc oxide nano particle is in the range of 70 nm. The SEM analysis shows that the shape of the nano particles is of nano rods. The quality and purity of the Zinc oxide nano particles are confirmed using XRD and EDAX spectral analysis. ► Zinc oxide nano particles synthesized by simple, economic and solvent free method. ► The organic dispersant glycerol initiates the reaction without any hazard. ► The absence of solvent gives pure zinc oxide nano particles.
