| titleOfInvention | A kind of hierarchical porous metal organic framework compound and its preparation method and application |
| abstract | The invention belongs to the field of separation and purification, and in particular relates to a hierarchical porous metal organic framework compound and a preparation method and application thereof. In the present invention, metal-oxygen clusters are first formed by metal ions and excess regulators, and then a small amount of low-pKa organic ligands are added, so that the coordination of regulators and metals can be incompletely replaced, thereby forming adjustable defect pores. By changing the types and relative contents of regulators, the changes of pore parameters such as pore size distribution and specific surface area were systematically explored. Without introducing specific groups, the STV with smaller molecular weight can be selectively adsorbed through pore size sieving, thereby realizing the purification of RA. The HP- NH2 -MIL-53 prepared by the invention not only provides a new material for the separation and purification of stevioside, but also is expected to provide a reference for the adsorption of other similar molecular weight substances, and has broad application prospects in the field of adsorption and separation. |
