CoOOH
CoOOH, also written cobalt oxyhydroxide, is a compound with the formula CoOOH. In many contexts it is described as cobalt(III) oxyhydroxide, a cobalt oxide–hydroxide species that forms under oxidizing conditions in basic media. It occurs as a pale brown solid and is often generated as an active phase in cobalt-based electrocatalysts.
Structure: CoOOH is related to layered transition metal oxyhydroxides. It consists of edge- and corner-sharing CoO6
Preparation: CoOOH is typically prepared by electrochemical oxidation of Co(OH)2 or cobalt oxide precursors in alkaline
Applications: A major use is as an active catalyst for the oxygen evolution reaction (OER) in alkaline
Properties and safety: CoOOH is relatively insoluble in water and stable under alkaline conditions, but can
