Zeolitic imidazolate frameworks of zinc, cobalt, and cadmium, including the framework ZIF-8 commercially sold as Basolite Z1200, exhibit surprising sensitivity to carbon dioxide under mild conditions. The frameworks chemically react with CO2 in the presence of moisture or liquid water to form carbonates. This effect, which has been previously not reported in metal-organic framework chemistry, p...

The use of antibiotics and dyes has resulted in severe water pollution health risks; therefore, it is urgent to remove them from sources. Among the most common methods for removing harmful contaminants, adsorption photodegradation are economical, simple, reusable. Due their high porosity, adjustability, crystal structure, metal-organic frameworks (MOFs) one effective adsorbents photocatalysts. ...

We report a new, simple and versatile method to obtain highly active MOF structures by carefully controlled postsynthesis thermal annealing. The active ZIF-8 structure shows highly enhanced CO2/N2 selectivity and stable cyclic CO2 uptake of ≥1.5 mmol g -1 at 1 bar and 25 °C with a heat of adsorption of ≥30 kJ mol, which is over 100% greater than the ≈0.7 mmol g and ≈17 kJ mol, respectively in t...

Gas transport through metal-organic framework membranes (MOFs) was switched in situ by applying an external electric field (E-field). The switching of gas permeation upon E-field polarization could be explained by the structural transformation of the zeolitic imidazolate framework ZIF-8 into polymorphs with more rigid lattices. Permeation measurements under a direct-current E-field poling of 50...

While bulk-sized metal-organic frameworks (MOFs) face limits to their utilization in various research fields such as energy storage applications, nanoarchitectonics is believed to be a possible solution. It is highly challenging to realize MOF nanobubbles with monocrystalline frameworks. By a spatially controlled etching approach, here, we can achieve the synthesis of zeolitic imidazolate frame...

Zeolitic imidazolate framework-8 (ZIF-8) is synthesized quickly at room temperature in methanol with the support of ultrasound. Porous ZnO also prepared via thermal treatment ZIF-8. The photocatalytic activities obtained materials are demonstrated methylene blue (MB) decomposition under UV radiation. characterized by means X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR)...

The synthesis of metal-organic framework (MOF) thin films has garnered significant attention during the past decade. By better understanding the parameters governing the nucleation and growth of such thin films, their properties can be rationally tuned, empowering their application as (reactive) membranes. Here, a combined AFM-vibrational spectroscopy research strategy is employed to detail the...

We report here the first example of ZIF materials synthesized in aqueous solution. The synthesis was performed at room temperature and typically took several minutes compared to hours and days in non-aqueous conditions. The obtained product were ZIF-8 nanocrystals having size of ~85 nm and showed excellent thermal, hydrothermal and solvothermal stabilities.
