Device for catalytic degradation of organic contaminants by using Ga2O3 thin film

Abstract

The invention relates to a device for catalytic degradation of organic contaminants by using a Ga2O3 thin film, and belongs to the field of organic contaminant photocatalytic degradation by semiconductor materials. A clamp groove is formed in a container; a quartz substrate on which a layer of Ga2O3 thin film material is deposited is clamped in the clamp groove, so that the Ga2O3 thin film is repeatedly used for catalytically degrading the organic contaminants. A quartz sheet is used as the substrate for Ga2O3 thin film growth; the quartz substrate is subjected to ultrasonic cleaning; radio frequency magnetron sputtering equipment is used for depositing a layer of Ga2O3 thin film material on the quartz substrate; a tubular furnace is used for performing annealing treatment on the Ga2O3 thin film material; the quartz sheet on which the Ga2O3 thin film is attached is put into the clamp groove of the container; under the ultraviolet illumination, the organic contaminant degradation is performed. A layer of Ga2O3 thin film in nanometer scale dimension is deposited on the quartz substrate by a magnetron sputtering method; the clamp groove is formed in the container for completing the fixation of the quartz substrate; the repeated utilization of the Ga2O3 material is realized.

Description

technical field [0001] The present invention relates to a method using Ga 2 o 3 The invention relates to a thin-film catalytic degradation device for organic pollutants, which belongs to the field of semiconductor material photocatalytic degradation of organic pollutants. Background technique [0002] With the development of industry, more and more organic pollutants (for example: perfluorooctanoic acid, dimethyl titanate, etc.) are discharged into the natural environment, threatening human safety. In order to degrade various organic pollutants, researchers use various methods such as heat treatment, reduction degradation, photochemical degradation and semiconductor photocatalytic degradation to degrade organic pollutants. The semiconductor photocatalytic process has the advantages of being able to be carried out at room temperature, low cost, high efficiency, and environmental friendliness. Many scientific research institutions at home and abroad have carried out research...
