Description
Technical field
The invention belongs to the technical field of nano material; Relate to a kind of preparation method of nano zine oxide; Be specifically related to a kind of preparation method with the nano zine oxide of the characteristics such as specific surface area is large, catalytic activity is high, stability is strong.
Background technology
Along with developing rapidly of modernization industry, a large amount of trade effluent containing organic poison is drained in the middle of environment, causes water resources to be subject to severe contamination, has threatened the survival and development of the mankind.Particularly some azoic dyestuffs, polyhalohydrocarbon and nitro-aromatic compound, their Stability Analysis of Structures, strong toxicity, intractability is very large, makes traditional environment project effective very micro-.Therefore, at present in the urgent need to finding new, more suitable effective method of wastewater treatment to make up the deficiency of conventional art.The appearance of metal oxide semiconductor photocatalysis oxidation technique has brought hope, and it mainly comprises TiO
2, ZnO, WO
3, SnO
2, Fe
2o
3deng N-type semiconductor material.This wherein, TiO
2because of its stable chemical nature, characteristics such as oxidation capacity is strong, nontoxic and become the most ripe, the most widely used nano photocatalyst catalytic material of research.But, along with the further investigation to photocatalytic degradation organic poison, it is found that nano-ZnO under many circumstances than TiO
2photocatalysis effect better.With TiO
2compare, ZnO has following advantage: (1) can absorb wider UV-light; (2) TiO
2be indirect band-gap semiconductor, transition of electron probability is lower, and quantum yield is lower, and catalyzed reaction process is also slow, is difficult to process the waste water that those concentration are high, quantity is large.On the contrary, ZnO is direct band-gap semicondictor, there is not these problems.(3) be difficult to it meet the condition that specific physicochemical property requires again while will keeping higher photocatalytic activity under that evenly load is on other carrier securely, and ZnO is just easy to adsorb on other carrier comparatively speaking.So ZnO can replace TiO
2become more promising new catalyst.
At present, the preparation method of nano level ZnO mainly can be divided three classes: solid phase method, liquid phase method, vapor phase process.Compared with other method, liquid phase method have simple, reaction system evenly, the feature that average particle size distribution is narrower, temperature of reaction is low of nanoparticle, be the prefered method preparing excellent nano ZnO material.But nano-ZnO, due to its huge surface energy, causes particle to be easy to reunite together, makes its pattern and size change, have a strong impact on the performance of the finished product.In addition, also can there is serious photoetch in it under the condition of UV-irradiation.Therefore will solve the problem, strictly must control its preparation condition--being introduced by different tensio-active agents in the preparation process of nano-ZnO is the method that a lot of scholar selects.Therefore, finding out suitable tensio-active agent is current problem demanding prompt solution, is the key point preparing less, the dispersed better nano ZnO material of particle diameter.
