Effect of organic compounds on morphologies ZnO nanostructures

Abstract

This paper reviews effects of organic compounds for synthesis of ZnO by reflux method as well as systematic investigation on the relationship between the structures of organic compounds on ZnO nanostructures morphology. The characteristic results revealed that using different template not only prevent a drastic increase in the crystallite size of the zinc species but also provide suitable conditions for the oriented growth of primary nanoparticles with especial morphology. It was found that the formation of ZnO with various morphologies could involve the role of preformed “nucleus" and used templates to control the growth rate of various facets of these preformed nucleuses. Depends on organic compounds and concentration of sodium hydroxide different morphologies of ZnO nanostructures were obtained. Three categories of organic compounds, carbohydrates, surfactant and ionic liquids were investigated as template.
