Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] A three-necked flask is selected as the reactor; first, zinc quantum dots are prepared in a dry method at room temperature by using a rolling vibration mill.

[0024] In the first step, add pure water to the three-necked flask A8, add zinc quantum dots with a scale of 3-5 nanometers, a purity of more than 95%, and a mass of 10 g into the three-necked flask B9, and open the valves A3, B4, and C5 , the argon gas is passed into the three-necked flask A8 and the three-necked flask B9 with a purity of more than 99.9% from the argon gas bottle 1 at a flow rate of 1 L / min, so that the argon is fully purged and completely replaced by the three-necked flask A8 and the three-necked flask B9 In the air, this step was repeated at least 3 times. The second step is to close valve A3 and valve C5, power on the ordinary electric heating jacket 6 and the intel...

Abstract

Disclosed is a preparing process for zinc oxide nano rods by zinc quantum dots, which utilizes zinc quantum dots to react with oxidation agent to prepare zinc oxide nano rods. The process comprises steps of putting zinc quantum dots which are 3-5 nm in size and over 95% in purity into a reacting device, completely substituting air in the reacting device with argon gas atmosphere, heating the reacting device to increase the temperature to 150 DEG C-300DEG C, keeping the temperature, thereby the argon gas carrying the oxidation agent can enter the reacting device and then achieving the contacting reaction with the zinc quantum dots, increasing flowing rate of the argon gas which carrying the oxidation agent, consciously providing oxidation agent to the reacting device until the reaction is finished, closing an oxidation agent inlet of the reacting device and leading pure argon gas into the reacting device, and then cooling the reacting device until the temperature reaches the indoor temperature, finally collecting the products in the reacting device, which is the zinc oxide nano. The preparing process has the advantages that the process needs no catalytic agent and does not pollute the products, the only secondary product in the preparing process is hydrogen gas which is non-pollution to environment, further the reaction temperature is low and the energy consumption is low and the obtained zinc oxide nano rods with specific growth direction are high in application value.

Description

technical field [0001] The invention relates to a method for preparing zinc oxide nano rods by using zinc quantum dots, and belongs to the technical field of nano material and nano structure preparation. Background technique [0002] Zinc oxide is a II-VI semiconductor material with important application value. It is one of the few oxide semiconductor materials that are easy to realize quantum size.
