Abstract

The invention relates to a method for preparing zinc oxide nanoshuttle, and provides a method for preparing a ZnO micro nano material with new appearance by a simple low-temperature hydro-thermal synthesis technology. The method comprises the following steps of: dripping a zinc nitrate solution into a hexamethylenetetramine solution slowly, dripping an ammonia water, and stirring; pouring the mixture into a reaction kettle, drying and diluting; and centrifuging a diluent to obtain a precipitate, drying the precipitate, and grinding to obtain the zinc oxide nanoshuttle. According to the zinc oxide nanoshuttle, the average value of the diameter of an intermediate section of a shuttle body is 500 nanometers, and the average length of the shuttle body is 1 to 2 micrometers. The zinc oxide nanoshuttle is pure in crystallization, and uniform in appearance and in size, and can be used for the fields of photochemical catalysis, gas sensitive sensors, moisture-sensitive sensors, photoelectronic devices, piezoresistors and the like.

Description

technical field [0001] The invention relates to a method for preparing zinc oxide nano shuttle. Background technique [0002] The structure and morphology of micro-nano materials have a great influence on the properties and applications of micro-nano materials. The preparation of micro-nano materials with specific structures has important academic significance and application value for the development of new fields of properties of micro-nano materials. Among numerous micro-nano materials, the micro-nano structure of ZnO has received extensive attention. Zinc oxide with micro-nano structure has attracted much attention due to its large specific surface area and good magnetic, optical, and electrical properties. It is expected to be used in many fields such as photocatalysis, gas sensors, humidity sensors, piezoresistors, and transparent electrodes. with broadly application foreground. [0003] At present, the preparation methods of ZnO micro-nanostructure mainly include c...
