Abstract :

Stable zinc oxide (ZnO) nanoparticles were synthesized by sol gel method from Zinc sulphate and hydrazine hydrate. Zinc sulphate was selected for the process, as it was the cheapest and readily available source of zinc. The complex formed as a result was zinc hydrazine acetate. The percentage of zinc in the complex, as estimated by titration with EDTA was 25.14%, as against the theoretical 26.42%. Zinc hydrazine acetate complex formed as a result is subjected to pyrolysis in a muffle furnace and ZnO nano particles were obtained. The resultant material was a white, photostable and non-hygroscopic, fine free flowing powder. The XRD patterns of these samples revealed that the required phase is present with a little amount of impurities. The particle diameters were found to be 38.5nm, 28.6nm and 31.0 nm. The particle size measurement was done by particle analyzer and was supported by XRD Scherer�s formula.
