Description
The invention relates to a kind of novel pore passage structure vanadium phosphate compound and synthetic method thereof.
The pore passage structure material is widely used in fields such as petrochemical complex, microelectronics and optical technology because of having performances such as unique crystalline structure and excellent absorption, ion-exchange, catalysis.Application the earliest, the pore passage structure material is a zeolite type aluminosilicate pore passage structure material the most widely.Along with society, economy and science and technology development, the zeolite type duct material of traditional with the silicon-oxy tetrahedron is structural framework can't satisfy the demands.The pore passage structure material just develops towards component and structure diversification and wide-aperture direction.
V-P-O system pore passage structure compound is the outer most important class pore passage structure material of present desilicate system.This class material is because the diversity of the mutability of vanadium valence state and ligand thereof and be connected flexibly with phosphorus oxygen tetrahedron, has that complex structure is changeable, the aperture big, characteristics such as absorption and catalytic property excellence.Be widely used on the basis of catalytic applications at laminate structure V-P-O compound, successfully synthesize that application potential is more huge, the V-P-O compound of tool three-dimensional open-framework system the beginning of the nineties in last century again, make the study on the synthesis of this compounds become the focus of present research.Kind surplus this system duct compound that has synthesized up to now reaches 30.Synthetic pore passage structure vanadium phosphate compound of the present invention is a kind of novel pore passage structure compound that report is arranged of not seeing as yet.This compound is a sap green transparent sheet-like crystal, and structural formula is: (NH
