Effect of Additives on the Thermal Decomposition Process of Zinc Citrate Complexes to ZnO
Abstract: Nanocrystalline ZnO has been synthesized through a citrate gel decomposition technique. The technique was modified by addition of additives such as ethylene glycol and CDTA (1,2 Cyclohexylenedinitrotetracetic acid). The conditions for obtaining nanocrystalline ZnO have been optimized. The influence of interaction additives-precursor gels on the evolution of structural features and particle morphology of ZnO have been studied by Infra red spectroscopy, thermal analysis TG-DTA & SEM. These properties of ZnO powders have been further supported by XRD. X-ray diffraction patterns showed the formation of wurtzite structure. The SEM analysis revealed that the morphologies of the as prepared ZnO were nanocrystalline, spherical in shape. When ethylene glycol is used as an additive particle size was found to be equal to 54 nm and in case of CDTA the particle size was 50 nm. It is found that additives addition was not much influencing the formation of ZnO nanostructure.
