cus/cdin 2 the s 4 /znin 2 the s 4 Microwave-assisted one-step synthesis of composite photocatalysts

Abstract

The invention discloses a CuS / CdIn 2 S 4 / ZnIn 2 S 4 The microwave-assisted one-step synthesis method of composite photocatalysts belongs to the technical field of the chemical industry. Using Zn(NO 3 ) 3 ·6H 2 O.In(NO 3 ) 3 ·4.5H 2 O.Cd(NO 3 ) 2 ·4H 2 O.Cu(NO 3 ) 2 ·3H 2 O.C 2 H 5 NS's five chemical reagent raw materials are mixed according to mass proportions and put into deionized water and stirred evenly. After microwave radiation reaction in the microwave reactor, they are repeatedly washed with deionized water and absolute ethanol, and then dried to obtain the final product CuS. / CdIn 2 S 4 / ZnIn 2 S 4 Composite photocatalyst. Its surface morphology, microstructure, and photocatalytic activity were measured. The product performance has been greatly improved in terms of photocatalysis for the degradation of organic pollutants methyl orange and photolysis of water to produce hydrogen. The microwave-assisted one-step synthesis method has the characteristics of short reaction time, uniform product generation, simple and practical production process, and stable and reliable sample and batch production performance.

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...
