Description

A kind of fungicide silver/silver chlorate/bismuth molybdate composite material preparation method
Technical field
The invention belongs to dirty water decontamination handles technical fields, handle microbial contamination in particular to photoactivation method The purified treatment of sewage, more particularly to a kind of fungicide silver/silver chlorate/bismuth molybdate composite material preparation method.
Background technique
Microorganism has tremendous influence to people's lives, their energy cleaning ambients make fertile soil, in food, change Work, pharmacy etc. play a very important role.However, also there are many can not be ignored microorganism while advantageous to the mankind Harm as microorganism usually caused by some disasters: for example bacterium and virus caused by disease, wound infection suppuration, micro- life Food spoilage caused by object is rotted and some precious articles are even damaged by corrosion etc..This will cause very big danger to society Evil, every year since the infection of bacterium and various viruses will will cause the death of ten hundreds of people.
Simple ultraviolet disinfection and disinfection by chlorine can not fully meet the needs of people, such as ultraviolet disinfection to certain purples The bacterium that outer light resists cannot reach good bactericidal effect, and a series of toxic by-products can be generated during disinfection by chlorine. Compared with two kinds of conventional methods, it is seen that photo-catalyst has non-selective sterilization and efficient quick and convenient equal remarkable advantages. At the same time, the visible light catalytic process of simulated solar irradiation can provide technical support for energy such as later use sunlights.Cause It is very necessary that this develops the various environment-friendly materials with antibacterial action.
Bi2MoO6As a kind of environmental-friendly, nontoxic novel photocatalyst, there is good visible light-responded property Matter.But single Bi2MoO6The recombination probability of electron-hole pair is larger in the photocatalytic process, needs to design it reasonable light Catalyst mechanism separates electronics, hole, reduces its recombination rate, and then improve Bi2MoO6Photocatalytic activity.
Ag/AgX (X C1, Br or I) was studied within a very long time in past and learns due to possessing higher dispersibility Person is used to modifying semiconductor catalysis material, to improve semiconductor internal structure.In addition to possessing good dispersibility, since Ag is mono- The presence of matter can provide a large amount of electronics for semiconductor material, and the connection between semiconductor and Ag/AgX plays bridge work With convenient for the migration of electron hole.These electronics change the migration path of electronics in original material in semiconductor substrate, this Sample just considerably increases the efficiency that is electrically separated of entire composite material, but photocatalytic activity is still to be improved.
