Metal‐Organic Frameworks in Monolithic Structures

Abstract

For the first time, the manufacturing of metal‐organic framework‐based monoliths using a two‐step process is reported. In a first experiment, the in situ synthesis of Cu 3 (BTC) 2 (benzene tricarboxylate [BTC]) on cordierite monoliths was chosen to immobilize Cu 3 (BTC) 2 . As this approach turned out to be of major disadvantages, the manufacturing of Cu 3 (BTC) 2 monolithic structures was chosen. The two‐step fabrication process included the manufacturing of a molding batch in a lab‐scale kneader followed by extrusion in a ram‐extruder. As additives, methyl hydroxyl propyl cellulose and methoxy functionalized siloxane ether were chosen. The resulting monolithic structures have a specific inner surface area of 370 m 2 /g and show a high mechanical stability of 320 N.
