Method for preparing a metal organic framework material

Abstract

A method for preparing a metal-organic framework material includes step (a) mixing ethylene glycol with recycled polyethylene terephthalate and performing alcoholysis treatment at 160°C to 200°C for 1 to 6 hours, followed by filtration and washing with water to obtain polyethylene terephthalate oligomers, and then sequentially drying and grinding the polyethylene terephthalate oligomers to obtain fragmented oligomers; step (b) mixing and grinding the fragmented oligomers with a metal salt, followed by thermal crystallization treatment at 100°C to 200°C for 3 to 48 hours to obtain a crude product comprising the metal-organic framework material; and step (c) washing the crude product with ethanol to obtain a product comprising the metal-organic framework material. A method for preparing a metal organic framework material, comprising step (a): mixing ethylene glycol with recycled polyethylene terephthalate and subjecting an alcoholysis treatment at 160°C to 200°C for 1 hour to 6 hours, followed by filtration and washing to obtain ethylene terephthalate oligomer, followed by subjecting the ethylene terephthalate oligomer to a drying treatment and crushing treatment sequentially to obtain a fragmented oligomer; step (b): mixing and grinding the fragmented oligomer with a metal salt, followed by subjecting a thermal crystallization at 100°C to 200°C for 3 hour to 48 hours to obtain a crude product including a metal organic framework material; and step (c): washing the crude product with ethanol to obtain a product including the metal organic framework material.
