In this paper, we present the new preparation method of nano-sized ZnO mate- rial by using high shear mulser, and research the influence of the experimental conditions on the morphology of nano-sized ZnO material, the experimental conditions, including reaction time, the pH value, concentration of zinc salt , rotating speed and agitation way of the mulser. This method of preparing ZnO nanostructures, compared with oth- ers, is simpler, more controllable, cheaper, easier to mass production,...
