This invention relates to a method for preparing ZnIn2S4 adsorbents, specifically an ultrasonic atomization method based on zinc indium sulfide, belonging to the field of catalytic material preparation technology. The invention aims to address the problems of poor chemical stability and weak surface reaction kinetics in existing sulfide preparation methods. The method involves using zinc chloride, indium trichloride tetrahydrate, and thioacetamide as raw materials, and employing a hydrothermal method combined with ultrasonic atomization at 0 MHz, 1.0 MHz, 2.4 MHz, and 3.0 MHz to prepare ZIS-0, ZIS-1.0, ZIS-2.4, and ZIS-3.0 photoadsorbents, respectively. This method utilizes the acoustic cavitation, hotspot, and aggregation effects of ultrasonic atomization to achieve precise particle size control, increase specific surface area, and shorten the crystallization cycle, significantly improving the adsorption efficiency of atrazine. The preparation process of this invention is mild and simple, and the obtained materials exhibit excellent atrazine adsorption properties in aqueous solutions.

The application relates to the technical field of nanomaterial preparation, in particular to a method for synthesizing a zinc-sulfur double-vacancy Zn3In2S6 photocatalyst, wherein specific-volume ammonia water is mixed with deionized water to form a solvent, zinc sulfate, indium trichloride and thioacetamide precursors are added, and after uniform stirring, one-step hydrothermal reaction is carried out at 160 DEG C for 12 hours, and the product is obtained through centrifugal washing and vacuum drying. Through the coordination induction effect of ammonia water, zinc vacancies and sulfur vacancies are in-situ constructed in the Zn3In2S6 crystal lattice, the introduced defect energy level is used as an electron trap to capture photo-generated electrons, carrier recombination is inhibited, and the surface active site is increased. The application can significantly improve the hydrogen production activity under visible light, the hydrogen evolution rate is 2.25 times that of the hydrogen production activity without adding ammonia water, and the application has the advantages of simple process route, excellent catalytic performance and strong structural stability.
