The preparation of photochemical catalyst and its research of photocatalytic activity.
Background technology
With industrialized development, people's increasingly concern for the environment pollution problem.Traditional environmental pollution substance treating method
The requirement of people is can not meet.A kind of cleaning is searched out, efficiently, energy-saving and environment-friendly sewage water treatment method is ground at people
The hot spot direction studied carefully.
TiO was found for the first time from 19722Since photocatalytic activity, the research of photocatalysis technology is always investigation of materials
Hot spot direction.Photocatalysis technology by its energy conservation and environmental protection, non-secondary pollution the advantages that for sewage processing provide one it is non-
Often good solution route.Conductor photocatalysis material can utilize in inexhaustible, nexhaustible solar energy processing air or
Poisonous and harmful substance in person's water improves environment, achievees the purpose that utilization of resources ecology.Currently, a variety of different semiconductor lights
Photocatalyst material is widely studied, such as bismuth tungstate, wolframic acid caesium etc..But wolframic acid antimony is extensive by its material source, price is low
It is honest and clean, as one of the hot spot material of photocatalysis research the advantages that no biotoxicity.
But there is also some defects for wolframic acid antimony photochemical catalyst, for example, its visible light utilization efficiency is low, and Gao get Guang
Raw electron-hole recombination rate, these all hinder its further application.In this background, wolframic acid antimony how is improved
Photocatalytic activity, at the Important Problems of research wolframic acid antimony photochemical catalyst.So far, it is used to improve there are many method
Its photocatalytic activity, such as:Pattern control, semiconductors coupling etc..But the photocatalysis efficiency of the modified wolframic acid antimony of the above method,
There are still some defects for stability.
