Description
Technical field
The present invention relates to technical field of inorganic material, particularly relate to the preparation method of a kind of nano zine oxide.
Background technology
Zinc oxide (ZnO), is commonly called as zinc white, is a kind of oxide of zinc.It is insoluble in water, dissolves in acid and highly basic.Zinc oxide is a kind of conventional chemical addition agent, is widely used in the making of the products such as plastics, silicate product, synthetic rubber, lubricating oil, paint, ointment, binding agent, food, battery, fire retardant.The band gap of zinc oxide and exciton bind energy are relatively big, and transparency is high, have the room temperature luminescent properties of excellence, all have application in the products such as the liquid crystal display of semiconductor applications, thin film transistor (TFT), light emitting diode.
Additionally, the zinc oxide of microparticle also begins to play a role in association area as a kind of nano material.Nano zine oxide is a kind of polyfunctional new inorganic material, and its granular size is about in 1～100 nanometers.Due to the granular of crystal grain, its Electronic Structure and crystal structure change, and create skin effect, bulk effect, quantum size effect and macroscopic view tunnel-effect and the feature such as the high grade of transparency, polymolecularity that macro object does not has.Discovered in recent years it show many specific functions at aspects such as catalysis, optics, magnetics, mechanics, make it have important using value in many fields such as pottery, chemical industry, electronics, optics, biology, medicine, there is particularity and purposes that common zinc oxide cannot compare.Nano zine oxide can be used for ultraviolet light masking material, antibacterial, fluorescent material, catalysis material etc. in fields such as weaving, coating.Due to a series of superiority of nano zine oxide and the most tempting application prospect, therefore research and development nano zine oxide has become many scientific and technical personnel's focus of attention.
Every annual meeting produces the zinc oxide 105 tons for industrial use, and production method mainly has three approach.
(1) indirect method (French)
After pure metallic zinc melts in graphite crucible, the steam of zinc is being formed higher than evaporation at a temperature of 907 DEG C (generally at about 1000 DEG C), steam is oxidized by oxygen generation zinc oxide in atmosphere, this oxidizing process can send the reduction of glittering light simultaneous temperature, and Zinc oxide particles is collected in a dust storage chamber by a cooling dispatch tube subsequently.This synthetic method was opened by Frenchman's LeClaire penetration and promotion in 1844, and therefore this method is also referred to as method national law.The product that this method obtains is usually the Zinc oxide particles of average-size 0.1 to several millimeters.By weight, the most most zinc oxide is manufactured by this method.
(2) direct method (U.S.)
Direct method is with the by-product after impure zinc compound such as Calamina or metallic zinc refine as raw material, and raw material first adds thermal reduction with carbon (such as anthracite) and generates zinc fume, and then steam indirect method is oxidized to zinc oxide.Because the purity of raw material is relatively low, so the product quality that the end product that direct method obtains compares indirect method is lower.
(3) wet chemical
A fraction of industrial products are to produce zinc carbonate or zinc hydroxide precipitation with pure zinc salt solution for raw material through chemical reaction.Precipitation passes through filtration, washing, at a temperature of 800 ° of about C, roasting obtains product after drying.
There is the method that many is specifically designed to synthesis scientific research and the zinc oxide of some special-purpose.Can these methods be divided into multiple according to the form of gained zinc oxide (block zinc oxide, zinc-oxide film, zinc oxide nanowire), synthesis temperature (close to the low temperature of room temperature or temperature close to the high temperature of 1000 ° of C), processing method (vapour deposition or solution growth) or other parameters.
The monocrystalline (volume reaches several cubic centimetre) of large volume is typically to prepare by Vapor-phase transport method (vapour deposition process), hydrothermal synthesis method or melt growth method.But the vapour pressure being because zinc oxide is the highest, so melt growth method is not suitable for cultivating Zinc oxide single crystal.The more difficult control of Vapor-phase transport method developing zinc oxide monocrystalline, this makes to tend to when preparing the monocrystalline of zinc oxide use hydro-thermal method.The preparation method of zinc-oxide film includes chemical vapour deposition technique, Metalorganic chemical vapor deposition method, electrochemical deposition method (Electrophoretic
Deposition), pulsed laser deposition, sputtering, sol-gal process, atomic layer deposition method, spray pyrolysis etc..But, the zinc oxide nano rod material diameter obtained is relatively thicker, and specific surface area is less, size heterogeneity, and dispersibility is the best, have impact on the application performance of nano zine oxide.
