Abstract
The invention provides a kind of insoluble sulfur hydrochlorate photochemical catalyst, the defects of insoluble sulfur hydrochlorate photochemical catalyst is due in the presence of its structure can form intermediate level in insoluble sulfur hydrochlorate in band, and then its photoresponse scope is expanded, so as to have excellent ultraviolet light photocatalysis performance.Insoluble sulfur hydrochlorate prepared by the present invention is 20% 50% to NO clearance under ultraviolet optical drive, it is 20% 70% to the clearance of methyl orange, and purification, wastewater treatment, solar energy reforming hydrogen manufacturing, sterilization or the medicine that can be applied to air pollution such as prepare at the field.The preparation method reaction condition of insoluble sulfur hydrochlorate photochemical catalyst provided by the invention is gentle, preparation method is simple, simple to operate, beneficial to its large-scale production.
Description
Technical field
The present invention relates to photocatalyst technology field, more specifically, is related to the system of insoluble sulfur hydrochlorate photochemical catalyst
Preparation Method and its application.
Background technology
Quickening and economic fast development with process of industrialization, environmental problem has turned into hinders social harmony sustainable
The problem of development, especially atmosphere polluting problem are increasingly notable.Traditional indoor pollution purification techniques is inhaled using activated carbon mostly
It is attached, but pollutant is simply transferred to solid phase by activated carbon from gas phase, post processing and regeneration issues be present.It is dirty in face of environment in recent years
The challenge of dye and pressure, Green Chemical Technology turn into human society can sustainable development inevitable requirement.In various differences
Green Chemical Technology in, photocatalysis is because its reaction condition is gentle, non-secondary pollution and directly can be reacted using Driven by Solar Energy
Turn into one of more promising technology etc. characteristic.

The band-to-band transition of body, which produces, works as photohole and electronics, an one-step inducing of going forward side by side chemical reaction.But the technology still has some defects, such as
The light quantum conversion efficiency of material is relatively low, photoresponse narrow range, it is seen that light utilization efficiency is low etc..Solution for these problems, grinds
The person of studying carefully is modified by various technological means to photochemical catalyst, and then improves photocatalysis performance；Or researcher finds newly
Photochemical catalyst.Recently studies have found that metal also shows excellent photocatalysis performance based on the plasma effect of itself, such as
Research finds Au, Ag, and Bi shows good photocatalysis performance.
Existing photocatalysis technology is only limitted to semiconductor and metal, but the photocatalysis performance of insulator is had not been reported.
