Angewandte Chemie, Volume 137, Issue 45, November 3, 2025.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 ...
