Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide grave public health consequences. Existing purification methods often cannot address this quickly and economically. Here we report cheap, stable metal-organic framework/polymer composite, Fe-BTC/PDA, that exhibits rapid, selective removal of large quantities such as Pb2+ Hg2+, from real world samples. In work, Fe-BTC treated dopamine, which undergoes spontaneous polymerization to polydopamine...
With the ever-increasing production of electronics, there is an ensuing need for gold extraction from sources other than virgin mines. Currently, are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts liquid sources. Here, we provide a blueprint design several highly porous composites made up metal–organic framework (MOF) template redox active, polymeric building blocks. One such composite, Fe-BTC/PpPDA, shown rapidly extract trace complex...
Hybrid polymer/inorganic membranes with dual transport pathways exhibit exceptional separation performance for carbon capture and non-classical gas behavior upon formation of a percolative network.
Metal-organic frameworks (MOFs) offer great promise in a variety of gas- and liquid-phase separations. However, the excellent performance on lab scale hardly translates into pilot- or industrial-scale applications due to microcrystalline nature MOFs. Therefore, structuring MOFs pellets beads is highly solicited timely requirement. In this work, general method developed for preparing MOF-polymer composite based an easy polymerization strategy. This adopts biocompatible, biodegradable...
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...
With the fast-growing accumulation of electronic waste and rising demand for rare metals, it is compelling to develop technologies that can promotionally recover targeted like gold, from waste, a process referred as urban mining. Thus, there increasing interest in design materials achieve rapid, selective gold capture while maintaining high adsorption capacity, especially complex aqueous-based matrices. Here, highly porous metal-organic framework (MOF)–polymer composite, BUT-33–poly( para...
Herein, a novel integrated adsorption–photoreduction system, which captures highly mobile and toxic hexavalent chromium (Cr(<sc>vi</sc>)) from real-world water samples reduces it to less benign Cr(<sc>iii</sc>) species, was designed.
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...
Making heterogeneous catalysis greener by improving nanoparticle stability in a MOF support modified with short polymeric chains.
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...

Under conditions, outperforms broad-spectrum carbon (BSC) uptake ammonia with approximately equivalent...
We report a one-step synthetic strategy to encapsulate copper nanocrystals (Cu NCs) in carboxylate-based metal–organic framework (MOF-74) construct Cu@Cu-MOF-74 hybrids. One of the hurdles realizing metal NC@MOF hybrids with uniform morphology and homogeneous NC spatial distribution by chemical transformation is precisely match dissolution rate MOF crystallization rate. Our study defines parameter space which controls this kinetic balance. Such an understanding generality our approach...
Perovskite solar cells (PSCs) have increased in power conversion efficiency the last 10 years, from ≈3% to now over 25%. While best perovskite photovoltaics remarkable efficiencies, Pb‐based absorber is likely problematic for commercialization due environmental concerns. To address this inevitable issue, a porous metal–organic framework (MOF) polymer composite applied, known as FeBTC/PDA that used “safe‐by‐design” panels. The material based on MOF scaffold containing polymeric metal binding...

Abstract MOF‐derived Co 3 S 4 /CN hollow nanoboxes (CN=nitrogen‐doped carbon) was used to catalyze the chemoselective reduction of nitroarenes anilines under mild reaction conditions with H 2 as reducing agent. The catalyst provides high conversion efficiencies and selectivities for a variety nitroarene substrates that contain electron‐donating or electron‐withdrawing substituents (in methanol at 60 °C). Further, nanobox inhibits both dehalogenation vinyl hydrogenation reactions, which are...
A metal–organic framework/polymer derived catalyst containing single-atom nickel species shows good performance for electroreduction of CO<sub>2</sub> to CO.

The traditional vacuum activation of covalent organic framework (COF) materials typically erodes the materials' crystallinity significantly and then reduces surface area isolated materials. Developing new methods for synthesizing robust COFs which could survive duration process is great practical significance.
