Abstract
Aluminophosphates represent an important group of micro- and mesoporous crystalline inorganic solids. Their zeolite-type framework structure contains a regular array of pores and channels which can accomodate a variety of host molecules. Due to their structural diversity and specificity and also because of their interesting physico-chemical properties, the aluminophosphates are potentially one of the most outstanding materials.They act like cation exchangers, as sorbents for organic and inorganic substances and, especially, like catalysts when there are metal atoms substituted into their framework.
The primary goal of the syntheses of aluminophosphates is to obtain large-pore materials that can further enable the course of reactions where large, sterically-demanding molecules are involved. Additional modification of the aluminophosphate framework by the introduction of transition metal atoms (commonly Co, Ni, Mn) and also of silicon yields products with improved, and in some cases, specifically-tailored catalytic properties.
A part of synthesis procedures is directed to the low-temperature formation of novel framework phosphates containing metal atoms other than aluminium (commonly Zn). The formation of many new metal phosphate structures is based on the ability of transition metal atoms to more easily adapt to variable surroundings and/or different coordination requirements.
