Study on Controllable Preparation and Performance of Regularized Zinc Oxide Micro - Nano Materials
Abstract: Zinc oxide is a kind of semiconductor material with important application value. In this experiment, chemical precipitation method was used to react with zinc nitrate hexahydrate and anhydrous ethanol in the oven at 180 ℃. Under the condition of changing the concentration of guide agent acetic acid and zinc nitrate A series of experiments were carried out. Finally, zinc oxide micro-nano materials with double-hexagonal pyramidal morphology were prepared. The performance of the samples was tested by electrochemical instrument. When the voltage range was 0-0.4v, the electrolyte was potassium hydroxide , The specific capacity of 5.1 F / g.
