Abstract
The application provides a Bi-CQDs / BiOCl composite material, a preparation method and application, and relates to the technical field of photocatalytic materials. The application first prepares carbon quantum dot anchored metal bismuth Bi-CQDs, then adds the carbon quantum dot anchored metal bismuth and bismuth nitrate pentahydrate into deionized water to stir and dissolve, then adds a saturated sodium chloride solution into the mixed solution and continues to stir magnetically; the obtained solution is transferred into an autoclave to perform hydrothermal reaction; after the obtained solution is cooled to room temperature, the sample is collected by centrifugation, the sample is washed by deionized water, the washed sample is collected by centrifugation, and drying is performed in a drying box to obtain the Bi-CQDs / BiOCl composite material. The preparation method is simple and easy to implement, the prepared Bi-CQDs / BiOCl composite material has photocatalytic capacity under full spectrum, and has wide application prospect.
