Abstract

The invention discloses a flower-like AgBiO3/NaBiO3 photocatalytic material synthesized by an in-situ method and application of the flower-like AgBiO3/NaBiO3 photocatalytic material, and relates to the technical field of photocatalysis. The material is a compound formed by compounding silver bismuthate and sodium bismuthate, the mass percent of the silver bismuthate in the compound is 10 to 50 percent. On the basis of insoluble sodium salt NaBiO3, an AgBiO3/NaBiO3 compound is constructed, the oxidizing property of NaBiO3 and AgBiO3 is utilized, the capability of removing pollutants synergistically through direct oxidation and catalytic oxidation is exerted, additional active species are provided in the degradation process, the total efficiency of pollutant removal is improved, and the method has the advantages of simple operation and low cost. The method has an important scientific theoretical value for the practical application of organic pollutant wastewater treatment.

Description

technical field [0001] The invention relates to the technical field of photocatalysis, in particular to an in-situ method for synthesizing flower-like AgBiO 3 / NaBiO 3 Photocatalytic materials and their preparation methods and applications. Background technique [0002] The environmental problem of organic pollution in the water phase seriously threatens the ecological sustainable development of society and human life and health, and has been highly valued by countries all over the world. my country's Environmental Protection Law sets strict standards for water-phase pollutants. Persistent organic pollutants in wastewater have high environmental toxicity, refractory degradation, transmission and accumulation effects through the food chain, and traditional biological or physical and chemical methods are difficult to effectively eliminate such pollutants. Therefore, the development of advanced technologies to effectively eliminate such pollutants is not only an important sc...
