Abstract

The invention discloses a metal-organic framework-phenolic resin composite material and a method for preparing the same, and belongs to the field of material chemistry. The metal-organic framework-phenolic resin composite material comprises metal-organic frameworks, phenolic resin or phenolic resin precursors. A mass ratio of the metal-organic frameworks to the phenolic resin or the phenolic resin precursors is 1:(0.5-10). The metal-organic framework-phenolic resin composite material and the method have the advantages that the metal-organic frameworks are used as cores for the metal-organic framework-phenolic resin composite material, the phenolic resin is used as a shell for the metal-organic framework-phenolic resin composite material, accordingly, porous materials can completely wrap the metal-organic frameworks, and the problems that existing metal-organic frameworks grow on the outer surfaces of existing porous materials and phase separation appears on composite materials can be effectively solved; the wall thickness, namely, the thickness of the phenolic resin, of the metal-organic framework-phenolic resin composite material prepared by the aid of the method can be completely regulated and controlled according to the quantity of the added phenolic resin precursors, and accordingly the hydrothermal stability and the structural stability of the metal-organic frameworks can be effectively enhanced.

Description

technical field [0001] The invention belongs to the field of material chemistry, and in particular relates to a metal organic framework-phenolic resin composite material and a preparation method thereof. Background technique [0002] Metal-organic frameworks (MOFs) are emerging crystal-like porous materials with a special three-dimensional pore structure formed by the self-assembly of metal ions and organic ligands. By adjusting the types of metal ions and the types of organic ligands, the types and structures of MOFs are also varied. Compared with traditional porous materials, MOFs have ultra-high specific surface area, high porosity, low density, controllable pore structure and size, and adjustable surface functional groups, so MOFs have great potential in storage, separation, catalysis and other fields. more and more widely used. [0003] In view of the weak thermal stability, hydrothermal stability and chemical stability of most MOFs, as well as the low pore utilizatio...
