Oxygen adsorption aluminophosphate

Several hundreds of synthetic zeolites (crystalline mieroporous aluminosilieates) and zeotypes (crystalline mieroporous ferrisilicates, gallosilicates, titanosilicates, isomorphously substituted aluminophosphates, etc.) have been sueeessfully synthesized in recent decades. All these mieroporous materials have tetrahedral coordination of their eentral atoms (Si, Al, P, Fe, etc.), which are interconnected with four oxygen bridges to form a three-dimensional crystal structure. These structures exhibit regular micropores with dimensions up to 1.0 nm and cavities, high surface areas, and adsorption capacities, and shape selectivity toward reactants, products, and transition states..
