Abstract

In article number 1801029, Kolleboyina Jayaramulu, Justus Masa, Wolfgang Schuhmann, Roland A. Fischer, and co-workers report simple and facile synthesis of cobalt-based 2D zeolite imidazole framework nanosheets [Co-ZIF-9(III)] by mechano-chemical grinding with subsequent liquid-phase exfoliation. The resultant 2D material exhibits highly efficient oxygen evolution reaction (OER) activity under alkaline conditions, attributed to increased accessibility of redox-active cobalt oxyhydroxide active sites with a nitrogen coordination environment N4CoOOH, and efficiently mimics Co-Porphyrin electrocatalysts.
