Preparation method of shell Zinc Oxide nano wire harness aggregate

The invention relates to a wet chemical preparation method for preparing ultrafine Zinc Oxide nano wire cluster aggregates by using metal zinc powder. The preparation method is as follows: adding zinc nitrate, sodium hydroxide and zinc powder in water, after mixing, the mixing of liquid and solid heat transfer water reactor, sealed reaction kettle. At room temperature or hydrothermal conditions, 1-12 hours, remove the solution and white products, centrifugal precipitation. Then, add pure water, repeated cleaning, centrifugal precipitation several times, natural drying, precipitation. The size of a single Zinc Oxide nanowire on the Zinc Oxide nanowire cluster can be regulated by temperature changes. The Zinc Oxide nanowire prepared by the method has low cost, simple process and equipment, and is safe and reliable. Versatility and operability. Scale production can be realized. The Zinc Oxide nanowires prepared by this method are free of surfactant and have rich surface defect states. They can be used in many fields such as catalysts, high sensitivity sensors and so on.
