Inorganic Salt Solution-Based Aerosols for Fabricating Honeycomb-Patterned Porous Membranes.

Porous membranes with uniform pore sizes have shown potential applications. Although the breath figure method is renowned for its simplicity, it requires high humidity conditions, presenting challenges in energy consumption and safety, especially in arid climates. This study introduces an approach that uses inorganic salt-based aerosols to successfully fabricate honeycomb-patterned porous membranes at low humidity levels, where pure water vapor cannot produce such structures.

Improved Interfacial Affinity and CO2 Separation Performance of Asymmetric Mixed Matrix Membranes by Incorporating Postmodified MIL-53(Al).

Asymmetric mixed matrix membranes(MMMs) with MOFs hold great application potential for energy-efficient gas separations. However, the particle aggregation and nonselective interfacial microvoids restrict the gas separation performance of asymmetric MMMs. Herein, nanoporous metal-organic framework (MOF) of MIL-53(Al) was modified with aminosilane after solvothermal synthesis.
