The invention provides an organic waste liquid treatment material which is characterized by being prepared by the following process: (1) adding sodium tripolyphosphate into a mixed solvent of cyclohexane and n-butyl alcohol, and ultrasonically mixing to form a blending system; (2) adding Bi salt, Fe salt, phosphoric acid and Mo salt in a certain molar ratio into the blending system, and then carrying out water bath reaction at 80-100 DEG C; (3) drying the obtained product, washing with deionized water and ethanol, and drying; and (4) carrying out heat treatment on the product in an air or oxygen atmosphere at the normal butanol degree of 300-500 DEG C, so as to obtain the nanorod-shaped Mo and P co-doped Bi2Fe4O9.
Description
technical field [0001] The invention belongs to the technical field of environmental pollution control, and in particular relates to a preparation method and application of a visible light catalyst. Background technique [0002] In recent years, with the rapid development of society and economy, organic pollution has become a worldwide problem. How to efficiently solve the problem of organic pollution is the hot spot and research focus of many researchers. Some organic substances such as dyes and pesticides exist in water and soil. Degradation seriously affects people's health and life. Photocatalytic technology utilizes semiconductor materials to degrade or mineralize pollutants into environmentally harmless products in a short time under the irradiation of ultraviolet and visible light, and accelerate the decomposition of organic pollutants. It is of great practical significance to develop high-performance photocatalytic materials. CN201710155915.3 discloses a method for...
