Problems solved by technology

After ingesting a large amount of methylene blue (MB) at one time, the human body will have adverse symptoms such as arrhythmia, dizziness and vomiting, limb paralysis and even shock. Not only that, even if it is ingested in a small amount, after a period of time, methylene blue (MB) is difficult to Decomposition will accumulate in the human body, and most of such people will suffer from Heinz body anemia, which is due to the effect of methylene blue (MB) on the shape of red blood cells, changing the shape of red blood cells, reducing the lifespan of red blood cells and the ability to transport oxygen
[0005] And so far there is no relevant Ag 2 MoO 4 with WO 3 Reports of composites possessing photocatalytic effects under light

Abstract

The invention discloses a preparation method of Ag2MoO4 catalytic composite and belongs to the technical field of photocatalysts. The preparation method includes: adding ammonium tungstate and CTAB (cetyl trimethylammonium bromide) into water to obtain solution A; dissolving nitric acid in ethanol / water solution to obtain solution B; pouring the solution B into the solution B, allowing reacting for a period of time, filtering, washing the filter cake, and drying the filter cake to powder C; calcining the powder C under certain conditions to obtain product D; dissolving the product D and certain silver nitrate in ethanol / water solution, adding certain p-aminophenol, stirring for dissolving to obtain solution E; adding ethanol / water solution of sodium molybdate into the solution E, and performing ultrasonic treatment, filtering, washing and drying to obtain Ag2MoO4 catalytic composite. The Ag2MoO4 catalytic composite is prepared by a simple chemical synthetic process; the preparation method has short reaction time, low energy consumption and low pollution and is suitable for large-scale production; the prepared powder has good dispersity, large specific surface area and good particleuniformity, and a new material and idea are provided for the existing treatment of water pollution.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials and photocatalytic materials, in particular to a preparation method and application of noble metal metal composite visible light catalytic materials, specifically an Ag 2 MoO 4 Preparation method and application of visible light catalytic composite material. Background technique [0002] Printing and dyeing, pharmaceutical, chemical and other industrial wastewater has a greater adverse impact on human health and the environment, especially the dye wastewater discharged from these industries. Due to the complexity of the dye structure, it is very difficult to degrade, which has always been a difficulty in water pollution control. The degree of environmental pollution in my country ranks among the top in the world, and the country has put forward new requirements for environmental governance planning during the "13th Five-Year Plan" period. The treatment of dye wastewater is facing new chall...
