Research Progress in Preparation and Application of Aluminophosphate Molecular Sieves

Aluminophosphate molecular sieves(AlPO4 n) is a new kind of porous materials, whose framework consists of aluminum phosphate. Due to its excellent thermal stability and long range order structural properties, it is often functioned as catalyst carrier for catalysis and as adsorbent for adsorption. Furthermore, modified aluminophosphate (MeAPO) itself can be used as solid acid catalyst. Aluminophosphate molecular sieves presents a good catalytic activity to organic reactions such as oxidation, group transfer and dehydration, therefore it is widely applied in the areas of petro chemistry and functional materials, etc., and is of great potential in industry. In this paper, recent research for synthesis and applications in each field of aluminophosphate molecular sieves is reviewed, focusing mainly on the product with special framework and applications for catalysis. Besides, the prospect of aluminophosphate molecular sieves is discussed.
