Unveiling the pore-size performance of metal organic frameworks (MOFs) is imperative for controllable design sophisticated catalysts. Herein, UiO-66 with distinct macropores and mesopores were intentionally created served as substrates to create advanced CdS/UiO-66 The pore size impacted spatial distribution CdS nanoparticles (NPs): tended deposit on external surface mesoporous UiO-66, but spon...

The rapid destruction of chemical threats, such as phosphate-based nerve agents, is of considerable current interest. The hydrolysis of the nerve-agent simulant methylparaoxon, as catalyzed by UiO-66 and UiO-67, was examined as a function of pH. Surprisingly, even though typical phosphate−ester hydrolysis mechanisms entail nucleophilic attack of the simulant by aqueous hydroxide, the rate of hy...

One of the major requirements in solid acid and base catalyzed reactions is that the reactants, intermediates or activated complexes cooperate with several functions of catalyst support. In this work the remarkable bifunctional behavior of the defective UiO-66(Zr) metal organic framework is shown for acid-base pair catalysis. The active site relies on the presence of coordinatively unsaturated ...

In this work, we report the incorporation of nickel oxide nanoparticles into a metal–organic framework (MOF) structure by solvent-free mechanochemical strategy. particular, zirconium-based MOF UiO-66 was modified with different Ni loadings and characterized using complementary techniques including X-ray diffraction (XRD), N2 porosimetry photoelectron spectroscopy (XPS). The catalytic potential ...

We describe the direct post-synthetic hydroxylation of UiO-66 through the photogeneration of hydroxyl radicals. Three approaches have been investigated, and levels of conversion up to 77% have been observed within 48 h.

Metal organic frameworks (MOFs) are frequently used as adsorbents in adsorption processes to remove dyes from effluent produced by the textile industry. Today, dye contaminants have become an important environmental problem. One of these is methylene blue (MB) and its removal wastewater a priority because it persistent nondegradable. MB many industries although has potential harmful effects on ...

Chemical environment control of the metal nanoparticles (NPs) embedded in nanocrystalline metal-organic frameworks (nMOFs) is useful in controlling the activity and selectivity of catalytic reactions. In this report, organic linkers with two functional groups, sulfonic acid (-SO3H, S) and ammonium (-NH3(+), N), are chosen as strong and weak acidic functionalities, respectively, and then incorpo...

We combine experiments and simulations to study the adsorption of water in several UiO-66 frameworks (ideal defect-containing structures). propose a new set charges for that accurately provides water-structure interaction at molecular level. The is suitable predicting ideal structure, providing first time, good agreement between experimental calculated isotherms. proposed procedure tuning point...
