Beschreibung
Zusammenfassung:	The invention relates to a method for preparing high-density zinc oxide nano granules. In the method, the high-density zinc oxide nano granules are grown by using diethyl zinc steam diluted by inert gas and steam of aqueous solution of hydrogen peroxide as reaction precursors, adopting an atomic layer deposition mode and using atomic layer deposition equipment, wherein the diethyl zinc steam and the steam of the aqueous solution of the hydrogen peroxide, serving as the reaction precursors, are alternately introduced into a reaction cavity in a pulse mode, and the two kinds of steam are blown and washed by using inert gas. The high-density zinc oxide nano granules are grown by using an atomic layer deposition technology, so the process is simple, and the production cost is low; the size ofthe nano granules can be accurately controlled; the zinc oxide nano granules with average diameter of about 5 to 25 nanometers, height of 2 to 10 nanometers and density of 1.010 to 1.010 cm can be obtained; and the zinc
