Photopolymerized Mixed Matrix Membranes for Liquid Organic Hydrogen Carrier Separation. [PDF]

Adv Sci (Weinh)
Photopolymerized membranes with high metal organic framework (MOF)/Pd activated carbon loading enable selective separation of hydrogen‐rich/lean liquid organic hydrogen carriers (LOHCs) under mild operational conditions. The employed fabrication approach yields stratified, multilayer structures with enhanced aromatic/aliphatic (toluene ...

Self-Aggregation Control of Porphyrin for Enhanced Selective Covalent Organic Network Membranes. [PDF]

Small
Highly conjugated porphyrin endow membrane with the regular pore and anti‐swelled structure for molecular separation, while large molecular size and excess aggregation lead to the large cut‐off (>800 Da). Here the stacking behavior of amino‐functional porphyrin is used to narrow pores and the chloride ligands to modulate the topology.
