Problems solved by technology

However, most of the current photocatalysts can only be excited by ultraviolet light, which accounts for only 3%~5% of sunlight, and cannot effectively utilize most of the visible light in sunlight. Therefore, the research on preparing efficient photocatalytic materials with visible light response It is very meaningful in photocatalytic degradation of organic pollutant methyl orange and photolysis of water to produce hydrogen.

Abstract

The invention discloses a microwave-assistant one-step synthesis method of a CuS / CdIn2S4 / ZnIn2S4 composite photocatalyst and belongs to the technical field of a chemical industry. The method comprises mixing Zn(NO3)3. 6H2O, In(NO3)3. 4.5H2O, Cd(NO3)2. 4H2O, Cu(NO3)2. 3H2O and C2H5NS according to a mass ratio, putting the mixture into deionized water, carrying out uniform stirring, carrying out microwave radiation through a microwave reactor, repeatedly washing the product through deionized water and anhydrous ethanol and carrying out drying to obtain the CuS / CdIn2S4 / ZnIn2S4 composite photocatalyst. Tests on surface morphology, a microstructure and photocatalytic activity prove that the product performances of organic pollutant methyl orange degradation and photocatalytically splitting of water into hydrogen are greatly improved. The microwave-assistant one-step synthesis method has the characteristics of short reaction time, uniform products and simple and practical production processes and has stable and reliable sample and volume production performances.

Description

technical field [0001] The present invention relates to a kind of CuS / CdIn 2 S 4 / ZnIn 2 S 4 The invention relates to a microwave-assisted one-step synthesis method of a composite photocatalyst, which belongs to the technical field of the chemical industry. Background technique [0002] Since Professor Fujishima and Honda discovered the use of TiO in 1972 2 Since the electrode can decompose water to generate hydrogen and oxygen under the irradiation of ultraviolet light, photocatalytic technology has attracted widespread attention of scientists from all over the world. However, most of the current photocatalysts can only be excited by ultraviolet light, which accounts for only 3%~5% of sunlight, and cannot effectively utilize most of the visible light in sunlight. Therefore, the research on preparing efficient photocatalytic materials with visible light response It is very meaningful in photocatalytic degradation of organic pollutant methyl orange and photolysis of wate...
