Abstract

A preparation method for a visible light photocatalyst powder and cloth from a bismuth-rich material comprises the steps: dissolving the bismuth-rich material and dithiocarbamate in solvents respectively, and adding the dithiocarbamate solution to the bismuth-rich solution drop by drop to produce a precipitate; filtering, washing and drying, to obtain a metal element-doped bismuth dithiocarbamate;dissolving the prepared metal element-doped bismuth dithiocarbamate in a good solvent, adding macromolecules, carrying out electrostatic spinning, and thus obtaining the cloth with a photocatalytic function. The prepared metal element-doped bismuth dithiocarbamate has the advantages of uniform morphology and size, good dispersibility, green and environmental protection, stability in air, water and most solvents, acid and alkali resistance, industrial mass production potential, and excellent photocatalytic pollutant degradation activity, and realizes the direct conversion and reuse of the bismuth-rich material; the photocatalytic cloth can effectively prevent the diffusion of the catalyst powder and realizes the effective recycling of the photocatalyst.

Description

technical field

[0001] The invention belongs to the technical field of material chemistry and photocatalysis, and in particular relates to a method for preparing visible light catalyst powder and cloth from bismuth-rich materials. Background technique

[0002] Due to the special properties of bismuth, and it is non-toxic and cheap, bismuth-based inorganic semiconductor photocatalytic materials, such as Bi 2 o 3 , BiOCl, BiOBr, BiOI, Bi 2 S 3 、BiPO 4 、BiVO 4 、 Bi 2 WO 6 、 Bi 2 MoO 6 etc., have received extensive attention due to their excellent visible-light photocatalytic activity. In recent years, some bismuth complex semiconductors, due to their low cost, easy synthesis, safety and environmental protection, and also have excellent photocatalytic activity, have great potential for practical photocatalytic pollutant degradation and water splitting for hydrogen and oxygen production, antibacterial, antibacterial, and antibacterial. Milling and other fields, the pros...
