Název v původním jazyce

Advancing High-Performance Mixed Matrix Membrane via Magnetically Aligned Polycrystalline Co0.5Ni0.5FeCrO4 Magnetic Spinel Nanoparticles for Effective H-2/CO2 and O-2/N-2 Gas Separation

Popis výsledku v původním jazyce

Gas separation matrix membranes (MMMs) benefit from a combination of a polymer matrix and heterogeneous solid or liquid (nano) additives. However, improvements in mechanical strength of membrane permeability or gas selectivity are often overbalanced by morphological deficiencies, such as aggregation or sedimentation of the nanofiller, due to poor control at the nano level. Here, the controlled orthogonal magnetic field deposition of self-invented spinel Co0.5Ni0.5FeCrO4 magnetic nanoparticles (SMNPs) into the cellulose triacetate (CTA) results in well-defined gas transport pathways in the membrane and enhances gas separation performances by expanding the effective-selective surface area. Contrariwise, the structural observation of the fabricated MMMs in the absence of the magnetic field shows precipitation and aggregation of the particles at the bottom of the membrane. The permeability and selectivity of the H-2/CO2 and O-2/N-2 gas pairs surpass the 2008 and 2015 Robeson upper bounds for the controlled embedding of the SMNPs series (up to 15 wt.%) while the neat CTA or MMM with a random non-controlled SMNPs distribution exhibits substantially lower permeability and selectivity values. This work contributes to the development of magnetic field casting as a facile technique that advances the gas transport properties of MMMs, efficient for air separation.
