Application of Crosslinked Polybenzimidazole-Poly(Vinyl Benzyl Chloride) Anion Exchange Membranes in Direct Ethanol Fuel Cells

Membranes, 2020
Crosslinked membranes have been synthesized by a casting process using polybenzimidazole (PBI) and poly(vinyl benzyl chloride) (PVBC). The membranes were quaternized with 1,4-diazabicyclo[2.2.2]octane (DABCO) to obtain fixed positive quaternary ammonium ...

Facile Synthesis of 20-nm-Thick ZIF-67 Films for Hydrogen Sieving Using β-Co(OH)₂ Precursor Nanosheets. [PDF]

Angew Chem Int Ed Engl
We report that highly dispersed β‐Co(OH)2 nanosheets (∼1‐nm‐thick) could be synthesized via a one‐pot reaction of ultradilute precursors (Co(NO3)2 + 2‐methyimidazole (HmIm) + H2O system) at room temperature in just 1 h. By using thin coatings of the as‐synthesized β‐Co(OH)2 nanosheets as self‐sacrificial templates, ∼20‐nm‐thick ZIF‐67 membranes could ...
