In this contribution, recent advances in the construction of MOF-polymer composites and their corresponding applications are briefly reviewed. The appearance such architectures is becoming prominent literature, due to fact that union these two dissimilar components can give rise a number desirable properties not necessarily achieved by individual components. For instance, while MOFs already boast unprecedented internal surface areas highly tunable pore structures, they often suffer from...
Metal-organic frameworks are of interest in a number host-guest applications. However, their weak coordination bonding often leads to instability aqueous environments, particularly at extreme pH, and hence, is challenging topic the field. In this work, two-step, post-synthetic polymerization method used create series highly hydrophobic, stable MOF composites. The MOFs first coated with thin layers polydopamine from free-base dopamine under mild oxygen atmosphere, which then undergoes Michael...
The adsorptive removal of dyes from industrial wastewater using commercially available adsorbents is not significantly efficient. Metal–organic frameworks (MOFs) offer outstanding properties which can boost the separation performance over current commercial and hence, these materials represent a milestone in improving treatment methods for dye water. Accordingly, this paper, recent studies modification MOF structures aquatic environment have been discussed. This study aims to elaborate on...
High internal surface areas, an asset that is highly sought after in material design, has brought metal–organic frameworks (MOFs) to the forefront of materials research. In fact, a major focus field on creating innovative ways maximize MOF areas. Despite this, large-pore MOFs, particularly those with mesopores, continue face problems pore collapse upon activation. Herein, we demonstrate easy method inhibit this problem via introduction small quantities polymer. For several mesoporous,...
Large language models (LLMs) have gained widespread interest due to their ability process human and perform tasks on which they not been explicitly trained. This is relevant for the chemical sciences, face problem of small diverse datasets that are frequently in form text. LLMs shown promise addressing these issues increasingly being harnessed predict properties, optimize reactions, even design conduct experiments autonomously. However, we still only a very limited systematic understanding...
Transition-metal phosphides have received tremendous attention during the past few years because they are earth-abundant, cost-effective, and show outstanding catalytic performance in several electrochemically driven conversions including hydrogen evolution, oxygen water splitting. As one member of transition-metal phosphides, Cox P-based materials been widely explored as electrocatalyts; however, their application traditional thermal catalysis rarely reported. In this work, cobalt...
This study aims to enhance the response and selectivity of zinc oxide (ZnO) gas sensors by its incorporating in MIL-100(Fe) as a support material. ZnO nanocomposites were synthesized impregnating MIL-100 with varying weight percentages (10% 20%). The fabricated underwent characterization through XRD, FTIR, DRS (UV-Vis), SEM/EDS, NH3-TPD techniques assess their material composition sensor performance. (UV-Vis) revealed significant decrease band gap, from Tauc analysis, accompanied 20%...
Metal–organic frameworks (MOFs) have attracted much attention in the past decade owing to their unprecedented internal surface areas, tunable topologies, designable surfaces, and various potential applications. One bottleneck field regarding MOF synthesis is controlling metal-containing secondary building unit (SBU) incorporated into structure. In this work we report characterization of five trimeric [M3(μ3-O)(CH3CO2)6]x clusters (where M = Fe3+, Cr3+, Fe3+/Cr3+, Fe3+/Co2+, or Fe3+/Ni2+ x +1...

Functionalizing metal–organic frameworks (MOFs) with amines is a commonly used strategy to enhance their performance in CO2 capture applications. As such, this work, two-step covalently functionalize NH2-containing MOFs short chain polyamines was developed. In the first step, parent MOF, Zn4O(NH2-BDC)3, exposed bromoacetyl bromide (BrAcBr), which readily reacts pendant -NH2 groups on 2-amino-1,4-benzenedicarboxylate (NH2-BDC2–) ligand. 1H NMR of digested MOF sample revealed that as much 90%...
The current generation of large language models (LLMs) has limited chemical knowledge. Recently, it been shown that these LLMs can learn and predict properties through fine-tuning. Using natural to train machine learning opens doors a wider audience, as field-specific featurization techniques be omitted. In this work, we explore the potential limitations approach. We studied performance fine-tuning three open-source (GPT-J-6B, Llama-3.1-8B, Mistral-7B) for range different questions....

We employ a synergistic material and process development strategy to improve the performance of single-cycle vacuum pressure swing adsorption (VPSA) for hydrogen purification CO2 separation from reforming-based synthesis. Based on process-informed adsorbent selection criteria, including high cyclic capacity selective uptake impurities like CO, N2, CH4 over H2, metal organic framework (MOF), Cu-TDPAT, is selected. First, isotherms CO2, CH4, N2 H2 are measured. Subsequently, column model used...
Metal-organic frameworks (MOFs) are promising materials for the photocatalytic H2 evolution reaction (HER) from water. To find optimal MOF a HER, one has to consider many different factors. For example, studies have emphasized importance of light absorption capability, optical band gap, and alignment. However, most these been carried out on very materials. In this work, we present combined experimental computation study HER performance set isostructural pyrene-based MOFs (M-TBAPy, where M =...
