2017年9月1日 · Here we show a route for the scalable production of nanometre-thick metal–organic framework (MOF) molecular sieving membranes, specifically via gel–vapour deposition, which combines sol–gel...

2019年11月14日 · In this perspective, we provide an overview of the structure, properties and applications of MOF monoliths. In particular, we explore the complex synthetic landscapes associated with MOF crystallization and discuss the synthetic factors leading to the formation of MOF gels, i.e. the precursor to sol–gel MOF monoliths.

4 天之前 · The gel network is uniformly distributed, featuring prominent mesoporous. Given the abundant metal sites within the MOF gel, [35] PEI gather around the gel network through coordination interactions, [36] forming a polymer-like aggregated morphology (Figure 2 b). After GA crosslinking, the network structure becomes more evident (Figure 2 c). The ...

2020年11月2日 · Here we report on the use of a metal–organic framework (MOF) gel membrane as a separator for organic batteries. The homogeneous micropores, intrinsic of the MOF-gel separator, act as...

2024年11月1日 · Key factors influencing the gelation of MOGs are comprehensively summarized. Solvent extraction parameters perturb the micro- and macro-structures of MOGs. Hierarchical pores and OMSs enable the effective adsorption of guest molecules. Optimization of MOGs promotes the capture, sensing and purification of pollutants.

2019年11月1日 · By this, MOF-based hydrogels and aerogels have achieved unparalleled results, outperforming ungelated MOFs materials in many aspects. This review presents current developments of MOF-based hydrogels and aerogels with emphasis on the specific categories and the synergistic effects of MOF-derived aerogels between MOFs and additional materials.

2020年9月1日 · Herein, a transparent MOF-based gel electrolyte (MGE) is demonstrated through the incorporation of 2-methylimidazole among MOF nanocrystals to prevent the strong light scattering of MOF nanocrystals. As a result, the gel electrolyte showed an improved average transmittance of ca. 82.2% compared with the MOF electrolytes without 2 ...

2017年12月11日 · Here we report the synthesis of a porous monolithic metal–organic framework (MOF), which after successful packing and densification reaches 259 cm 3 (STP) cm −3 capacity. This is the...

2024年11月6日 · 该研究以题为“ Boosting Hydrogen Transport in Mixed Matrix Membranes through Continuous Spillover Via Pd-Functionalized MOF Gel Networks ”为题发表在最新一期的《Advanced Functional Materials》上。 氢气溢流是一种促进氢气高效传输的独特机制，首先在催化领域取得了显著成效。 在本文中，我们首次将这一机制应用于膜分离技术。 Pd@ZIF-67凝胶网络中的钯纳米颗粒（Pd NPs）通过氢气的解离作用，将氢气分子解离为原子氢。 随后，这些原 …

The urgent need for efficient CO2 capture technologies to mitigate climate change has driven the advancement of membrane-based separation systems. We report a mixed matrix membrane design through the in-situ growth of a ZIF-8 gel network within a Pebax-1657 matrix. By tuning the solvent ratio and concentration of modulator, ZIF-8 gel …
