Description
Technical field
The present invention relates to a kind of Bi2S3The preparation method of nano material.
Background technology
Bismuth sulfide（Bi2S3）It is a kind of V-VI race's direct band-gap semicondictor material of the high anisotropy of layer structure
（Eg=1.30eV）, there is stable, nontoxic, environmental-friendly, intrinsic photo-conductivity, Peltier effects and nonlinear optical response
Etc. a series of excellent performances, there is potential application prospect in fields such as photoelectricity, thermoelectricity, photocatalysis, biomedicines.Bi2S3Nanometer
Material not only has above-mentioned novel structure and special photoelectric property, can also make its taboo by the regulation and control in size and dimension
Bandwidth Eg is continuously adjusted from the 1.3eV of body material to 1.8eV, can preferably be matched with solar radiation spectrum, and have
Higher absorption coefficient（105cm-1）, therefore Bi2S3Nano material is highly suitable to be applied for solar cell.It has reported at present
Bi2S3The synthetic method of nano material mainly has thermal decomposition method, hydro-thermal method, sonochemical method, colloid chemistry methods, surfactant
Auxiliary law and chemical vapour deposition technique etc..In these synthetic methods, hydro-thermal method regular, good dispersion with product morphology,
Controllability and reproducible is grown, the advantages that easy to operate and reaction process is pollution-free, is a kind of preferable nano material preparation side
Method.Using these synthetic methods, the Bi of different morphologies has successfully been prepared2S3Nano material, such as nanometer rods, nanotube, nanometer
Necklace and plate-like and the structures such as flower-shaped.However most Bi before2S3Be required in the synthesis of nano material using template or
Surfactant regulates and controls out different size and shapes, not only increases the complexity of experiment in this way, also adds experiment
Cost.
