Description
Technical field
The present invention relates to one and prepare a cube block CeO
2the molte-salt synthesis of nano material, relates to specifically with NaNO
3with NaF be melting salt system preparation cube block CeO
2the molte-salt synthesis of nano material, belongs to field of nano material preparation.
Background technology
Rare earth is a kind of very important strategic resources, in Chinese national economy construction, have very important effect, is often used to high-quality precision and sophisticated technology industry.In recent years, along with the development of nanotechnology, many traditional materials show the using value made new advances.Such as, traditional rare earth material and nanotechnology are combined, prepares rare earth nano material, and explore it and receive much attention in the application of the environmental catalysis chemical fields such as motor-vehicle tail-gas improvement.
Cerium oxide (CeO
2) as a kind of light rare earths oxide compound, there is purposes widely.At present, CeO
2the year consumption nearly ten thousand tons of powder, its application performance is not only relevant with purity and structure, and granularity, dispersiveness and pattern etc. are to CeO
2the application of powder also has larger impact.Therefore, the CeO of high purity, polymolecularity and regular pattern is prepared
2nano particle is further broaden application field and the key improving utilising efficiency.For the preparation of CeO
2the method of nano particle mainly comprises: the precipitator method, hydrothermal method, microemulsion method and sol-gel method etc.Owing to having higher surfactivity, in drying and roasting process, easily make CeO
2nanoparticle agglomerates or sintering, thus cause gained nano particle diameter to increase, weaken CeO
2the catalytic performance of nano particle.
Molte-salt synthesis is the novel method of the preparation nano material that development in recent years is got up.The method has that cheaper starting materials is easy to get, preparation process is simple, cost is low, product purity is high and output advantages of higher.Such as: (Guo Guibao, Wang Zhengde, Hu little Ping wait .CeO to Guo etc.
