Problems solved by technology

The disadvantage of this material is that the composition is relatively single, and the thermal stability is poor; when the template is removed by heating, the skeleton collapses
According to the literature search, it is known that using organic amines as templates to introduce other metals into the zirconium phosphate skeleton, making it an inorganic material with multiple reactive centers has not yet been reported in literature and patents.

Description

technical field [0001] The invention relates to a class of trivalent metal zirconium phosphate inorganic material MeZrPO-12, wherein MeZrPO-12 is the serial number of the inorganic material. [0002] The present invention also relates to the synthesis method of the above-mentioned materials. [0003] The present invention also relates to the above-mentioned material being applicable to the fields of ion exchange, adsorption, catalysis and other inorganic functional materials. Background technique [0004] In 1964, A.Clearfield et al first reported the synthesis of zirconium phosphate crystals, preliminarily determined the composition and structure of the crystals, believed that it had a layered structure and was defined as α-type, and the chemical formula was α-Zr(HPO 4 ) 2 ·H 2 O (abbreviated as α-ZrP), its layered structure was later confirmed by single crystal X-ray diffraction structure analysis. In 1968, A. Clearfield et al reported zirconium phosphate crystals whos...
