Description
Summary:We report an allyl-decorated and hydrazine-connected covalent organic framework (COF-AO, 1), which could support Pd nanoparticles (Pd NPs) to generate Pd@COF-AO, 2. The incorporation of 2 with thiol-functionalized polysiloxane (termed as PSI-SH) via thiol–ene click reaction provided the stand-alone and elastic membrane (3). The obtained COF-involved and Pd NP-loaded covalently linked membrane of 3 is robust, permanently porous, uniform, processable, and water permeable. Moreover, it can be used to construct highly efficient membrane-based microreactor for continuous-flow operation to catalyze chlorobenzenes (CBs) dechlorination in water at room temperature. The provided approach herein allows the processability and practical application of the powdered COF materials to be feasible.
