Abstract Proton‐conducting materials are an important component of fuel cells. Development new types proton‐conducting is one the most issues in fuel‐cell technology. Herein, we present newly developed materials, modularly built porous solids, including coordination polymers (CPs) or metal–organic frameworks (MOFs). The designable and tunable nature allows for fast development this research field. Design synthesis their unique proton‐conduction properties discussed.
The postsynthetic modification strategy is adopted to demonstrate for the first time syntheses of catalytically active chiral MOPMs from a preassambled achiral framework, MIL-101, by attaching L-proline-derived catalytic units open metal coordination sites host framework. Various characterization techniques (including PXRD, TGA, IR, and N(2) absorption measurements) indicated that are successfully incorporated into keeping parent framework intact. new show remarkable activities in asymmetric...
The organic molecular porous material 1 obtained by recrystallization of cucurbit[6]uril (CB[6]) from HCl shows a high CO2 sorption capacity at 298 K, bar. Most interestingly, showed the highest selectivity over CO among known materials so far. remarkable may be attributed to exceptionally enthalpy adsorption (33.0 kJ/mol). X-ray crystal structure analysis adsorbed revealed three independent sites: two in 1D channels (A and B) one cavities (C). molecules site A near wall interact with...
Cucurbituril-based organic molecular porous materials with 1D channels filled water–acid arrays were synthesized. The isostructural showed different proton conductivity depending on the nature and number of acid molecules present in channels. highly anisotropic conduction behavior was studied by single-crystal measurements.
Carbonization of zinc containing metal-organic frameworks produces porous carbon materials with an interesting linear relationship between the Zn/C ratio precursors and surface area resulting materials.

Heavy metal ion removal from wastewater constitutes an important issue in the water treatment industry. Although a variety of nanomaterials have been developed for heavy via adsorption, adsorption capacity, efficiency, and material recyclability still remain challenge. Here, we present novel Fe3O4@DAPF core-shell ferromagnetic nanorods (CSFMNRs) Pb(II) aqueous solutions; they were prepared by facile surface modification twin-like Fe3O4 using 2,3-diaminophenol formaldehyde (DAPF)-based...
Development of carbon-based materials has received tremendous attention owing to their multifunctional properties. Biomaterials often serve as an inspiration for the preparation new carbon materials. Herein, we present a facile synthesis bioinspired graphene oxide-like 2D-carbon flake (CF) using natural resource, waste onion sheathing (Allium cepa). The 2D-CF was further decorated with crystalline Fe3O4 nanoparticles applications. Superparamagnetic (7 nm) were well-dispersed on surface...

Abstract To prepare materials with high CO 2 adsorption, a series of hierarchical LTA zeolites possessing various mesopore spaces that are decorated alkylamines was designed and synthesized. The highest uptake capacity achieved when (3‐aminopropyl)trimethoxysilane (APTMS) grafted onto the zeolite having largest mesopores. Owing to contributions both alkylamine groups surfaces active sites in zeolites, amount can be taken up on these is much higher than for conventional aminosilicas such...
Deuterium has been recognized as an irreplaceable element in industrial and scientific research. However, hydrogen isotope separation still remains a huge challenge due to the identical physicochemical properties of isotopes. In this paper, partially fluorinated metal-organic framework (MOF) with copper, so-called FMOFCu, was investigated determine efficiency capacity for deuterium extraction from mixture.
