MOF-based hierarchical porous materials, methods for preparation, methods for pore regulation and uses thereof

摘要

A series of MOF-based hierarchical porous material, namely IPD-mesoMOF-1˜9, based on nanoscale MOFs of MIL-100(Al, Fe, Cr, Sc and In), MIL-53(Al), HKUST-1, DUT-5, DUT-4, MIL-101(Cr), MIL-101NDC(Cr), MIL-101BPDC(Cr) and MIL-110 respectively, forming the permanent interparticle porosities by using close (or relatively close) packing, and preparation methods thereof. Modulated or functionalized IPD-mesoMOFs can be applied for gas adsorption and molecule separation (such as CH4- and CO2-adsorption, gasoline/diesel desulfurization and purification), catalyst loadings and molecular recognition/immobilization of biological macromolecules and enzymes.

1. A MOF-based hierarchical porous material IPD-mesoMOF-1˜9, characterized in that:
the MOF-based hierarchical porous material is based on the following MOF-type structure: MIL-100(Al, Fe, Cr, Sc and In), MIL-53(Al), HKUST-1, DUT-5, DUT-4, MIL-101(Cr), MIL-101NDC(Cr), MIL-101BPDC(Cr) and MIL-110; the MOF-based hierarchical porous material comprises micropores, in which the structural features and pore aperture of the micropores vary with regard to the MOF-type; the MOF-based hierarchical porous material is based on MOF nanoparticles with particle size less than 120 nm; and the MOF nanoparticles with particle size less than 120 nm are capable of generating the desired interparticle mesopores of 2-50 nm under close or relatively close packing conditions.
