Embodiment 1

[0033] This embodiment provides a method for preparing zinc oxide nanowires, which specifically includes the following steps:

[0034] Weigh 28g of zinc oxide, 11.6g of aluminum powder, 30.7g of cuprous oxide, and 11.6g of tin oxide (the moles of zinc oxide, aluminum powder, cuprous oxide and tin The ratio is 16:20:10:4), after uniform mixing in the mixer for 2 hours, pour figure 1 The graphite crucible 4 in the shown reaction chamber 2 is placed in a combustion synthesis device, ignited with a tungsten wire to initiate a self-propagating high-temperature synthesis reaction, and the reaction ends within ten seconds. After natural cooling, the reaction chamber, A large number of gray zinc oxide nanowires were collected in graphite crucibles and gas-permeable covers.

Embodiment 2

[0036] This embodiment provides a method for preparing zinc oxide nanowires, which specifically includes the following steps:

[0037] Weigh 31.6g of zinc oxide, 11.6g of aluminum powder, 30.7g of cuprous oxide, and 5.8g of tin oxide (the content of zinc oxide, aluminum powder, cuprous oxide and tin The molar ratio is 18:20:10:2), after uniform mixing in the mixer for 2h, pour figure 1 The graphite crucible 4 in the shown reaction chamber 2 is placed in a combustion synthesis device, ignited with a tungsten wire to initiate a self-propagating high-temperature synthesis reaction, and the reaction ends within ten seconds. After natural cooling, the reaction chamber, A large number of gray zinc oxide nanowires were collected in graphite crucibles and gas-permeable covers.

Embodiment 3

Abstract

The invention relates to the technical field of nanomaterial preparation, in particular to a zinc oxide nanowire and a preparation method thereof. The zinc oxide nanowire is made by burning a combustion agent, a propellant, a zinc source agent and an additive. The preparation method of the invention does not need special raw materials and equipment, is simple to operate, requires low technical level requirements on equipment and production personnel, has large output, and is suitable for batch preparation.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a zinc oxide nanowire and a preparation method thereof. Background technique [0002] Nano Zinc Oxide (ZnO) is a multifunctional new inorganic material with a particle size between 1-100nm. Due to the miniaturization of crystal grains, the surface electronic structure and crystal structure change, resulting in surface effects, volume effects, quantum size effects, macroscopic tunnel effects, and high dispersion that macroscopic objects do not have. Magnetism, mechanics and other aspects show many special functions, which make them have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology, medicine, textile, coating, etc., and can be used as ultraviolet light shielding materials, antibacterial agents, fluorescent Materials, photocatalytic materials, etc., have advantages that ordinary zinc oxide does not hav...
