Název v původním jazyce

Stimuli-responsive of magnetic metal-organic frameworks (MMOF): Synthesis, dispersion control, and its tunability into polymer matrix under the augmented-magnetic field for H-2 separation and CO2 capturing applications

Popis výsledku v původním jazyce

Single-crystal magnetic-responsive core-shell MOF by grafting Fe3O4 nanoparticles onto the UiO-66-NH2 and their controlled embedding into gas separation mixed matrix membranes was reported. Obtained results confirmed the stimuli-responsive character of the MMOF during their dispersion of MMOF in a well-defined arrays structure in the PMMA matrix. Contrarily, an absence of a magnetic field results in the MMOF aggregation and sedimentation of the particles at the bottom of the membrane. Compared to the non-controlled ones, gas permeability increased by 26.2% for CO2 and 76.67% for H-2, and selectivity increased 2.95 and 1.49 times for the CO2/N-2 and H-2/CO2 gas pairs, respectively. Moreover, obtained permeability-selectivity values for the H-2/CO2 gas pairs overcome the appropriate modified 2008 Robeson upper bound. (C) 2022 Hydrogen Energy Publications LLC.
