Membrane separation technology is considered an effective strategy to remove pollutants in sewage. However, it remains a significant challenge to fabricate inexpensive membranes with high purification efficiency. Therefore, the present study proposes the integration of silk nanofibrils (SNFs) and polydopamine⊂metal-organic framework (PDA⊂MOF) nanop...

Single crystalline (SC) hollow metal-organic frameworks (MOFs) are excellent host materials for molecular and nanoparticle catalysts. However, due to synthetic challenges, chemically robust SC hollow MOFs are rare. This work reports the construction of a defect-free and chemically stable SC hollow MOF, MOF-801(h), through templated growth from a un...

A rapid surface sealing strategy has been developed for the encapsulation of a homogeneous catalyst, phosphotungstic acid (PTA), in a mesoporous metal-organic framework (MOF), MIL-101(Cr). This new surface polymerization method utilizes non-solvent-induced phase separation to concentrate and direct polyamine and dianhydride monomers onto MOF partic...

This work presents a rapid and generalizable method to construct well-defined MOF@polymer core-shell composite particles to improve the processability of the MOF. The method utilizes a one-step coating process called...

We report a dual-interfacial engineering approach that uses a sub-20 nm polycrystalline MOF-74 shell as a transition phase to engineer the MOF-polymer interface. The application of a shell MOF layer divides the original single interface problem into two interfaces: MOF-MOF and MOF-polymer, which can be individually addressed. The greater external s...

Metal-organic frameworks (MOFs) is a promising class of sorbent materials for swing adsorption gas separation. However, although sorption kinetics plays a major role in column breakthrough experiments, it is rarely studied with MOF materials. This is largely because the synthesis of uniform, yet separation relevant MOFs is a challenging task. Here,...

Constructing core-shell metal-organic frameworks (MOFs) based on two topologically distinct MOFs is a great way to increase MOF material complexity and explore their new functions. However, such nucleation process is energetically less favored compared to epitaxial growth due to mismatched unit cell parameters. Here, two kinetic factors, nucleation...
