The invention provides a method for preparing
zinc oxide nanometer hollow spheres in caustic
corrosion reaction. The method is mainly characterized in including using the solution of Zn(Ac)2 as the initial reactant first, adjusting the pH value to 11.5-14 by adding
ammonia, using
ethanol as the
solvent, finally forming the nanometer hollow spheres in the
hydrothermal reaction between Zn(NH3)4<2+> and excessive
ammonia at a high temperature. The entire reaction has simple material, easy operation, no need for any complex instrument
processing, convenience and rapidness, which is a method of rapidly preparing the
zinc oxide nanometer hollow spheres. The obtained hollow spheres have narrow size distribution and good dispersibility with an external
diameter of 600 nm and an internal
diameter of 200-300 nm. The caustic
corrosion reaction is adopted to synthesize
zinc oxide nanometer hollow spheres in the method, thus agglomeration phenomenon caused by an aging
machine is obviated, complex operation steps of
organic reaction synthesis,
contamination and disturbance to objective material zinc oxide caused by the complex operation steps are obviated. The method is obviously characterized in high
production rate, rapidness, easiness, convenient operation, low cost and environment friendliness.
