AlPO4based
AlPO4-based materials are inorganic compounds and composites in which aluminum phosphate (AlPO4) forms the primary structural unit. They may be crystalline, such as berlinite-type AlPO4, or amorphous aluminum phosphate, and can also include doped or substituted variants, as well as composites with other oxides. Si-containing aluminophosphates, known as SAPO materials, are a notable family that combines silicon with the aluminophosphate framework.
The structure of AlPO4-based materials is characterized by strong Al–O–P linkages that create networks with varying
Synthesis methods include precipitation from aluminum salts and phosphoric acid, hydrothermal or solvothermal crystallization, and sol-gel
Applications of AlPO4-based materials span catalysis, adsorption, and separation. They serve as catalyst supports and active
