Summary: Ce-La-MOFs composites synthesized via hydrothermal method were utilized as an adsorbent for fluoride removal from aqueous solutions. The effects of various factors such as preparation molar ratio, adsorption period, and initial fluoride concentration were investigated. The adsorption mechanism was deduced from the analysis of thermodynamics, kinetics models, and characterization techniques. The results demonstrated that Ce-La-MOFs exhibited high selectivity for F- and reached a removal efficiency of over 90% under optimal conditions. The adsorption process followed Langmuir and pseudo-second-order models, and involved ion exchange and electrostatic interaction mechanisms. Furthermore, Ce-La-MOFs composites showed favorable regeneration ability with a significant adsorption capacity after multiple regeneration cycles.

Summary: In this study, we synthesized and scaled up Ru catalysts using high porosity MOF templates grown on graphitic carbon supports via solvothermal synthesis. Thermal treatment of the MOF resulted in well-dispersed Ru nanoparticles that were fully stabilized by in-situ graphitization of the surrounding carbon. The resulting catalyst showed significant improvement in activity for low-temperature NH3 synthesis, and the production of catalysts was scaled up from 1 g per batch to 200 g per batch.

Summary: The competition between NH3 and H2O in metal-organic frameworks (MOFs) for adsorption sites is explored using in situ infrared spectroscopy and ab initio calculations. The results show that NH3 can displace metal-bound H2O at high NH3/H2O ratio, and vice versa. It is also found that the vibrational modes of adsorbed NH3 are significantly affected by water molecules. These findings provide mechanistic insights into molecular coadsorption processes in MOFs and have implications for NH3 removal efficiency assessment in humid conditions.

Summary: This study investigates the structure-modulator relationship in the synthesis of thorium-based MOFs using different modulators and the ligand H4ATC. The results show that formic acid and acetic acid compete with H4ATC to form NU-52 and NU-54, while trifluoroacetic acid and benzoic acid result in NU-53 and NU-55. The identity and amount of modulator play a crucial role in determining the Th-based MOF structures with H4ATC as the coordinated ligand.

Summary: The cerium-zirconium mixed oxides synthesized by Flame Spray Pyrolysis (FSP) exhibit higher catalytic activities compared to those prepared by precipitation method. It is suggested that FSP enables surface enrichment in cerium oxide interacting with zirconium oxide, leading to a higher concentration of adsorbed methanol at the surface, which explains the superior catalytic activity of the catalysts prepared using this method. This method is expected to generate mixed oxides with high surface area and different catalytic performances compared to those prepared at lower temperatures due to their metastable nature.

Summary: Efficient separation and catalytic processes in nanoporous adsorbents require fine tuning of gas adsorption in their porosity. This experimental study using Si-rich zeolites demonstrates the pivotal role of hydroxyl concentration in vapor adsorption, showing a transition from nonwetting to wetting as the hydroxyl surface density reaches a critical value. The concept of a critical concentration is extended beyond water to different polar substrates, providing a foundation for the rational design of hydrophobic adsorbents.

Summary: Metal-Organic Frameworks (MOFs) are seen as potential breakthrough adsorbents for heat-pump applications due to their type V water adsorption isotherms and large water capacities. However, heat and mass transport limitations, as well as Knudsen diffusion at the grain scale, may impact the performance of Al(OH)-fumarate. Heat transfer within the bed packing and to the heat exchanger are also factors affecting the slow adsorption and desorption kinetics.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations.
