A backbone support structure and capillary effect-induced high-flux MOF-based m...
Yang, Xue; Chen, XinYi; Su, Xiaolei; Cavaco-Paulo, Artur; Wang, Hongbo; Su, JingMetal-organic frameworks (MOFs) based mixed-matrix membranes (MMMs) exhibited an excellent promise for separating dye molecules and salt ions due to their permeability and selectability. However, controlling interfacial compatibility between the polymer and MOFs remained challenging, and MOF-based MMMs were poorly processable. Herein, the dual-bath coagulation method was developed to form the polyvinylidene flu...
Synthesis of phenylalanine/manganese-copper supramolecular sheets with laccase-...
Chen, Xinyi; Yang, Xue; Su, Xiaolei; Cavaco-Paulo, Artur; Su, Jing; Wang, HongboEnzyme mimics with laccase-like activity showing excellent stability and tolerance have attracted extensive interest in phenolic pollutants treatment. Herein, we presented a mild and convenient strategy for the preparation of laccase-like sheets (denoted as Mn-F-Cu) inspired by the supramolecular self-assembly of the transition metals manganese, copper, and L-phenylalanine (F) under room temperature, alkaline c...
Polydopamine bridging encapsulated laccase on MOF-based mixed-matrix membrane f...
Yang, Xue; Chen, XinYi; Su, Xiaolei; Cavaco-Paulo, Artur; Wang, Hongbo; Su, JingMixed-matrix membranes (MMMs) exhibit significant potential for dye/salt separation. However, overcoming the trade-off between permeability and selectivity, as well as membrane fouling, remains a formidable task. In this work, a biocatalytic membrane was prepared using polydopamine (PDA) as a bridge connecting the metal-organic framework (MOF)-based MMM and immobilized laccase. The MOF-based MMM featured an int...
Anti-biofouling membrane coated with polyvinyl alcohol/sodium carboxymethylcell...
Yang, Xue; Chen, Xinyi; Su, Xiaolei; Cavaco-Paulo, Artur; Wang, Hongbo; Su, JingBiofouling is the most severe challenge for separation membranes. In this study, a metal-organic framework (MOF)-based mixed-matrix membranes (MMMs) with polyvinyl alcohol (PVA)/sodium carboxymethylcellulose (CMC)/tannic acid (TA) hydrogel coating exhibited a comprehensive anti-biofouling property and high efficient for dye/salt separation. For the hydrogel layer, ethanol inhibited the cross-linking of the hydr...
