Abstract:
AFI type molecular sieve is an important member of the families of inorganic microporous materials, due to better selectivity properties and structures diversification, it has a good application prospect in the fields of the catalytic properties and adsorption separation, and so on. A large number of studies have shown that it has a direct connection between the sizes, morphologies and the properties of the molecular sieves, at the same time the sizes and morphologies directly affect application effects of molecular sieves. Microwave synthesis have a series of advantages, for instance: fast heating, heating uniformity, narrow particle size distribution of the product, the characteristics of phase selectivity, energy saving and environmental protection. The microwave synthesis is introduced into the morphologies research of inorganic microporous compounds,as will play an important role. In this paper, AlPO4-5 molecular sieve with different morphologies is successfully prepared under the condition of microwave radiation, in addition, SAPO-5, CoAPO-5, FeAPO-5, MnAPO-5, and MgAPO-5 CuAPO-5 are successfully prepared by the same way. This paper expounds the influence of synthesis condlitions on the products’ morphologies in detail.
