Molecular design of double crosslinked sulfonated polyphenylsulfone /polybenzimidazole blend membranes for an efficient hydrogen purification

Rational Tuning of Zirconium Metal–Organic Framework Membranes for Hydrogen Purification

“…[1] Thed ominant technology for H 2 production is through steam reforming of natural gas.H owever,t he purification of hydrogen from the common contaminants (for example,CO 2 ,N 2 ,CH 4 ,and H 2 O) is ar equisite for the practical applications such as hydrogen fuel cells. [2] Them embrane separation process has attracted significant interest owing to its efficient energy consumption and smaller physical footprints compared with traditional separation technologies,s uch as distillation and liquid-phase absorption. Polymeric membranes dominate the current membrane market for gas separation;h owever,t heir desirable performance is limited by the well-known trade-off between permeability and selectivity.…”

Molecular sieving using metal–polymer coordination membranes in organic media

“…2d), which showed two characteristic peaks for -NHand ]Nat around 400 and 398 eV, respectively. 29,30 Moreover, the deconvolution of these spectra (Fig. S2 †) showed that the peak corresponding to ]N-(at 398 eV) decreased as the copper(I) iodide concentration increased, whereas the -NH-(at 299 eV) peak remained quasi unchanged.…”

Designing organic solvent separation membranes: polymers, porous structures, 2D materials, and their combinations

“…PBI has high T g (410 -430°C), good mechanical properties, and strong size-sieving ability derived from the ]#] stacking and H-bonding interactions. 32,114,[162][163][164][165] However, PBI is not stable in NMP, DMF, and DMAc. 111,166 Therefore, a variety of cross-linking methods have been developed to improve chemical stability as well as the size-sieving ability.…”
