Description
Technical field
The present invention relates to a kind of photocatalyst.
The invention still further relates to the preparation method of above-mentioned catalyst.
The invention still further relates to photocatalysis degradation organic contaminant technical field.
Background technology
Since in recent years, environmental problem has become as the significant problem that the mankind are faced.With titanium dioxide as representative half
Conductor catalysis material has the advantages that low cost, good stability, becomes the study hotspot of photocatalysis field, can be widely applied to
Sewage disposal.But, the energy gap of titanium dioxide is larger, only utilizes the ultraviolet light in sunlight, and the most sun
Light energy is all distributed in visible region.Therefore, how effectively to make full use of solar energy to curb environmental pollution increasingly by people
Attention.In the preparation method of conductor photocatalysis material, it is employed in this area research current using hydro-thermal method
Main method.But the method preparation time length and being easy in preparation process due to being heated inequality and producing impurity, defect etc..
Therefore, urgently seek a kind of simply time-consuming few photocatalyst preparation method.
Content of the invention
Present invention aims to the band gap of BiOCl photocatalyst proposes one kind not only can more fully utilize too
Sun energy, and can solve the problem that the preparation method of problem of environmental pollution BiOCl/BiOBr composite photo-catalyst.
Meaning of the present invention is to provide a kind of efficient BiOCl/BiOBr photocatalyst, can keep good stablizing
Property and higher catalysis activity, simultaneously preparation method simple, time-consuming less, low cost.
The preparation method of the BiOCl/BiOBr photocatalyst that the present invention provides is as follows:
A certain amount of hexadecyltrimethylammonium chloride (CTAC) is dissolved in ethylene glycol (solution 1);By a certain amount of ten
Six alkyl trimethyl ammonium bromides (CTAB) are dissolved in ethylene glycol (solution 2);A certain amount of bismuth nitrate is dissolved in (solution in ethylene glycol
3);Then respectively solution 1 and solution 2 are slowly dropped in solution three, after continuing stirring a period of time, put into microwave reactor
In 10 minutes power be 200W.After cooling, the pelleting centrifugation that will produce, uses distilled water and absolute ethanol washing, then successively
60 DEG C of vacuum drying obtain corresponding BiOCl/BiOBr photocatalyst.
Under visible radiation, the photocatalytic activity test concrete grammar of rhodamine B degradation and condition are as follows:
The Photocatalytic oxidation activity of catalyst is to carry out in homemade photo catalysis reactor.Reaction condition is:Room temperature is normal
