Abstract

The invention discloses a preparation method of a germanium selenide nano material and application of the germanium selenide nano material. The preparation method of the germanium selenide nano material comprises the following steps of: mixing GeI4 and oleylamine, and sequentially carrying out magnetic stirring, vacuumizing, heating and heat preservation; and injecting selenourea into the mixture of GeI4 and oleylamine, refluxing the reaction mixture at a high temperature in an inert gas environment, cooling to room temperature, washing with acetone, alcohol and deionized water in sequence, and drying to obtain germanium selenide nanoparticles. According to the preparation method of the germanium selenide nano material, selenourea and GeI4 are subjected to a redox reaction in an oleylamine solvent at a high temperature to synthesize germanium selenide nano particles, the germanium selenide nano particles are cooled to room temperature, washed with acetone, alcohol and deionized water and dried to obtain the germanium selenide nano particle material, and the whole preparation method is simple to operate, environment-friendly, pollution-free and easy for industrial production. The germanium selenide nano material disclosed by the invention is applied to degradation of organic pollutants.

Description

technical field

[0001] The invention relates to the technical field of new materials, in particular to a preparation method of a germanium selenide nanometer material and an application of the germanium selenide nanometer material. Background technique

[0002] In recent years, with the development of industry, a large amount of waste water and other pollutants are increasing, and the quality of water, soil and air is gradually deteriorating, especially organic dyes that are difficult to degrade. There are tens of thousands of organic dyes, especially in antibiotics. Tetracyclines are refractory and persistent. If they are discharged without degradation, the dyes can enter the human body through other channels, eventually endangering human health and causing environmental pollution. At present, the methods for degrading organic dyes include: adsorption filtration method, photocatalysis method and so on. In order to meet people's urgent requirements for a green and environme...
