Description
Technical field
The present invention relates to a kind of method that solid phase prepares cadmium sulfide-silver sulfide heterojunction nanometer material, belongs to nano material
Preparation field.
Background technology
In recent years, the physicochemical characteristics of the uniqueness that nano material has due to itself and receive researcher
Extensive concern.Cadmium sulfide as a kind of highly important semiconductor nano material, because which has special light, electricity, thermal and magnetic etc.
Property, and huge application prospect is shown in fields such as light emitting semiconductor device, nonlinear optical material, photocatalysis.However,
Easily there is the rotten candle phenomenon of light in cadmium sulfide nano material, and then have influence on its performance and practical application.Research finds, using different
Matter structure can improve the rotten candle phenomenon of its light to a certain extent, so using the visible light-responded feature of cadmium sulfide, with other
It is common sulfide hetero-junctions thinking that the stable semi-conducting material of physical and chemical performance builds heterojunction structure.Wherein, nanoscale
Sulfuration ag material has at aspects such as light absorbs, sensing, catalysis more wide because producing larger specific surface and quantum size effect
General and important potentiality application, is that this can effectively improve the rotten candle phenomenon of its light by compound to cadmium sulfide and silver sulfide.
At present, the method for preparing cadmium sulfide-silver sulfide heterojunction nanometer material includes hydro-thermal method and microwave method etc., but this
A little methods are related to the deficiencies such as experiment condition harshness, energy consumption height, thus develop a kind of simple, high yield, eco-friendly synthesis side
Method is still very urgent.Rare earth chemical method has the high and advantages of environment protection of simple to operate, low cost, yield,
Become a kind of effective ways of nano materials.
Content of the invention
It is an object of the invention to provide a kind of method that solid phase prepares cadmium sulfide-silver sulfide heterojunction nanometer material, is
Cadmium sulfide-silver sulfide heterojunction nanometer material is prepared as sulphur source with thioacetamide using rare earth chemical reaction.The party
Nano material prepared by method effectively improves the light corruption candle phenomenon of cadmium sulfide, and it is compound with silver sulfide to achieve cadmium sulfide.
The invention discloses a kind of method that solid phase prepares cadmium sulfide-silver sulfide heterojunction nanometer material.The side of the present invention
Method is to be ground together to react and then to realize cadmium sulfide-silver sulfide heterogeneous with metal cadmium salt, metal silver salt and thioacetamide
The rare earth chemical preparation of knot nano material.
The method that the present invention prepares cadmium sulfide-silver sulfide heterojunction nanometer material with thioacetamide as sulphur source solid phase, behaviour
Work is simple, do not use solvent, high yield, low cost, is that the preparation of cadmium sulfide based composites provides a kind of new thinking.
