Coloured water body is not only set to hinder aquatic plant that sunlight is absorbed and utilized, but also methyl orange itself is toxic, this is to contaminated water body periphery
The existence of animals and plants causes serious threat.
Photocatalytic method is a kind of Novel sewage treatment method.Its principle is: under the conditions of certain wavelength light is shone, semiconductor light
Electron transition in catalysis material valence band leaves hole to conduction band in valence band.Subsequent light induced electron and hole and ion or
Molecule combines, and generates the living radical with oxidisability or reproducibility.This living radical can will be organic in water body
Macromolecular mineralising is water and carbon dioxide, to achieve the purpose that degradable organic pollutant.Photocatalytic method is compared to traditional dirt
Method for treating water has many advantages.Firstly, hole is easily acted on hydrone when carrying out photocatalysis in water body, oxidisability is formed
Extremely strong hydroxyl radical free radical.The free radical can be extremely suitble in processing sewage with all organic substances of the mineralising of non-selectivity
Organic principle.It, can be with by seeking the catalysis material of visible light absorbing secondly, photocatalytic method is using luminous energy as energy source
Solar energy is effectively utilized, it is economic and environment-friendly.Finally, photochemical catalyst itself does not change in catalytic reaction process, therefore can
To recycle, there is practicability.
Sb2MoO6Have the characteristics that chemical property is stable, cheap and production is easy, is light-catalysed ideal material.But
It is that the material is not applied to photocatalysis field also so far.It is an object of the invention to probe into Sb2MoO6Photocatalytic activity,
And provide a kind of Sb2MoO6The preparation method of catalysis material.
