Developing a synthetic methodology for the fabrication of hierarchically porous metal-organic monoliths that feature high surface area, low density and tunable porosity is imperative mass transfer applications, including bulky molecule capture, heterogeneous catalysis drug delivery. Here we report versatile facile route towards ultralight micro/mesoporous aerogels based on two-step gelation framework nanoparticles. Heating represents key factor in control versus crystallization...
Porous materials combining high hydrophobicity, large surface area, as well and uniform pore size are very useful but rare. The nanoporous zeolitic metal azolate framework, RHO-[Zn(eim)2] (MAF-6, Heim = 2-ethylimidazole), is an attractive candidate thought to be unobtainable/unstable. In this work, the supramolecular isomerism of [Zn(eim)2] thoroughly studied using a rapid solution mixing reaction [Zn(NH3)4](OH)2 Heim, which enables MAF-6 with crystallinity, purity, thermal/chemical...
Advanced oxidation processes (AOPs) are increasingly applied in water and wastewater treatment. Understanding the role of reactive species using probes quenchers is one main requirements for good process design. However, much fundamental kinetic data reactions with lacking, probably leading to inappropriate probe quencher selection dosing. In this work, second-order rate constants over 150 such as •OH, SO4•-, Cl• chemical oxidants free chlorine persulfate were determined. Some previously...
Abstract Herein, an amino‐acid‐boosted biomimetic strategy is reported that enabled the rapid encapsulation, or co‐encapsulation, of a broad range proteins into microporous metal–organic frameworks (MOFs), with ultrahigh loading efficiency. It relies on accelerated formation prenucleation clusters around via metallothionein‐like self‐assembly. The encapsulated maintained their native conformations, and structural confinement within porous MOFs endowed enzymes excellent bioactivity, even in...
Abstract Embedding an enzyme within a MOF as exoskeleton (enzyme@MOF) offers new opportunities to improve the inherent fragile nature of enzyme, but also impart novel biofunctionality MOF. Despite remarkable stability achieved for MOF‐embedded enzymes, embedding patterns and conversion enzymatic after entrapment by have only received limited attention. Herein, we reveal how affect bioactivity encapsulated in ZIF‐8. The enzyme@MOF can maintain high activity when encapsulation process is...
Abstract Constructing inorganic–organic hybrids with superior properties in terms of water adsorption and activation will lead to catalysts significantly enhanced electrocatalytic activity the hydrogen evolution reaction (HER) environmentally benign neutral media. Herein, we report SiO 2 –polypyrrole (PPy) hybrid nanotubes supported on carbon fibers (CFs) (SiO /PPy NTs–CFs) as inexpensive high‐performance electrocatalysts for HER Because strong electronic interactions between PPy, uniquely...
Phase boundary engineered CeO<sub>2</sub>/CeN is synthesized and used as a high performance photocatalyst for photo-thermocatalytic degradation of organic pollutants in wastewater.
Photosynthesis of hydrogen peroxide (H2O2) in ambient conditions remains neither cost effective nor environmentally friendly enough because the rapid charge recombination. Here, a photocatalytic rate as high 114 μmol⋅g-1⋅h-1 for production H2O2 pure water and open air is achieved by using Z-scheme heterojunction, which outperforms almost all reported photocatalysts under same conditions. An extensive study at atomic level demonstrates that electron transfer realized improving photoresponse...
Abstract Nature programs the structural folding of an enzyme that allows its on-demand biofunctionality; however, it is still a long-standing challenge to manually modulate enzyme’s conformation. Here, we design exogenous hydrogen-bonded organic framework conformation cytochrome c, and hence allow non-native bioactivity for enzyme. The rigid framework, with net-arranged carboxylate inner cage, in situ installed onto native c. resultant nano-biointerface changes previously not achieved...
Abstract The fulfillment of a high quantum efficiency for photocatalytic CO 2 reduction presents key challenge, which can be overcome by developing strategies dynamic attachment between photosensitizer and catalyst. In this context, we exploit the use coordinate bond to connect pyridine-appended iridium molecular catalysts reduction, is systematically demonstrated 1 H nuclear magnetic resonance titration, theoretical calculations, spectroscopic measurements. mechanistic investigations reveal...
Abstract Crystallization of biomacromolecules-metal-organic frameworks (BMOFs) allows for orderly assemble symbiotic hybrids with desirable biological and chemical functions in one voxel. The structure-activity relationship this crystal, however, is still blurred. Here, we directly identify the atomic-level structure BMOFs, using integrated differential phase contrast-scanning transmission electron microscopy, cryo-electron microscopy x-ray absorption fine techniques. We discover an obvious...
In this work, we synthesized a two-dimensional fluorescent covalent–organic framework (TFPB–TTA COF) nanosheet by selecting and designing reactive monomers to realize the dual-functional processing of nitrophenols. The staggered benzene ring, triazine structure, imine bond (C═N) TFPB–TTA COF can capture free nitrophenols through hydrogen bonding conjugation interaction, then, photoinduced electron transfer fluorescence resonance energy (FRET) between affects emission COF, realizing sensing...
In the past decade, scientists sought to engineer nanomaterials with natural enzymes-like biological function, and searched for newfangled applications. Herein, we show first example of utilizing a bimetal metal–organic framework (MOF-818) platform mimicking Cu/Zn-superoxide dismutase (Cu/Zn-SOD), an important antioxidant enzyme that specifically scavenges superoxide anions. Experimental data theoretical calculations reveal high Cu/Zn-SOD-like activity MOF-818 results from synergistic...
Abstract Mimicking the bioactivity of native enzymes through synthetic chemistry is an efficient means to advance biocatalysts in a cell‐free environment, however, remains long‐standing challenges. Herein, we utilize structurally explicit hydrogen‐bonded organic frameworks (HOFs) mimic photo‐responsive oxidase, and uncover important role pore environments on mediating oxidase‐like activity by constructing isostructural HOFs. We discover that HOF with suitable geometry can stabilize spatially...
