Problems solved by technology

[0002] As an emerging crystalline porous framework material in recent years, metal-organic framework materials (MOFs) are three-dimensional periodic network porous materials formed by the process of self-assembly of metal ions and organic ligands, due to their large specific surface area , with adjustable pore size and a large number of metal open sites have shown their prominence in many application fields; however, the synthesis of MOFs materials is currently mainly focused on the use of hydrothermal or solvothermal synthesis methods, which have high energy consumption and long synthesis cycles; Compared with this, MOFs materials can be rapidly prepared in large quantities by reflux stirring method, which provides a better synthesis strategy for the practical application of MOFs materials in the future.

Abstract

The invention relates to a method for rapidly synthesizing HKUST-1 by utilizing a reflux stirring method. The method is characterized in that the metal organic framework material HKUST-1 can be rapidly prepared in a reflux stirring mode, the PXRD peak appearance position of the metal organic framework material HKUST-1 is kept consistent with that of a standard simulation card, crystal particles are in an octahedral shape, the particle size is mainly concentrated between 10 micrometers and 20 micrometers, and the agglomeration phenomenon basically does not occur. Compared with HKUST-1 prepared by a solvothermal method, the HKUST-1 prepared by the method has the characteristics of rapid and large-scale preparation, and has very high practical value.

Description

technical field [0001] The invention relates to a method for rapidly synthesizing HKUST-1 by using a reflux stirring method. Background technique [0002] As an emerging crystalline porous framework material in recent years, metal-organic frameworks (MOFs) are three-dimensional periodic network porous materials formed by the process of coordination self-assembly of metal ions and organic ligands. , tunable pore size and a large number of metal open sites have emerged in many application fields; however, the current synthesis of MOFs materials is mainly concentrated in the use of hydrothermal or solvothermal synthesis methods, which have high energy consumption and long synthesis cycles; In contrast, the reflux stirring method can rapidly prepare MOFs in large quantities, which provides a better synthesis strategy for the practical application of MOFs in the future. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a kind of method that is...
