Embodiment 1

[0021] The diameter of the reactor is 20 mm, and the length of the electric furnace is 200 mm. The flow rate of argon (99.9%) is 115 sccm, the flow rate of oxygen (99.9%) is 0.1 sccm, graphite material is used as the container and deposition substrate of zinc powder, the particle size of zinc powder is less than 25 μm (pure zinc content >99.2%), the thickness of zinc powder is placed About 1.5mm. The reaction temperature is 680°C, and the reaction time is 20 minutes. Prepared in batches to obtain pure hollow spherical and hemispherical zinc oxide, the form of the product is as follows figure 1 shown.

Embodiment 2

[0023] The diameter of the reactor is 20 mm, and the length of the electric furnace is 200 mm. The flow rate of argon (99.9%) is 80 sccm, and the flow rate of oxygen (99.9%) is 8 sccm. The graphite material is used as the container and deposition substrate of the zinc powder. The particle size of the zinc powder is less than 25 μm (pure zinc content> 99.2%). 3mm; reaction temperature 600°C, reaction time 40min. The sea urchin-shaped zinc oxide hollow sphere material was prepared in batches. The material is an assembly of zinc oxide nanowires and hollow spheres. The shape of the product is as follows: figure 2 shown.

Abstract

The invention relates to the lot synthesis method for nano / micron ZnO hollow ball. Wherein, with Zn powder or ZnO powder as material, using simple chemical gas phase deposition to synthesize directly the product; adjusting the evaporating temperature of material, product deposition temperature or adding catalyst to realize original assembly synthesis. The product has well physical chemical performance and wide application in electronic device or other fields.

Description

technical field [0001] The invention belongs to the interdisciplinary technical field of nanometer materials and inorganic synthesis chemistry, and relates to a method for batch synthesis of zinc oxide nano / micron hollow spheres for synthesizing nanometer or micrometer zinc oxide functional materials by a vapor phase deposition method. Background technique [0002] Since Frank Cruso ([Science, 282, 1111, 1998]) developed a soft template method to synthesize hollow silica spheres in 1998, hollow sphere synthesis technology has developed rapidly. [0003] As a special nano or micro material, the hollow sphere material has huge potential application prospects in many fields, and one of its main functions is as a packaging material to control the diffusion and delivery of other materials. Specifically, these nano / micro materials can be used for color retention of paints and pigments, controlled release of drugs in biomedicine, as catalysts for waste treatment, and as encapsulati...
