Electrocatalytic water oxidation with a tris-chelating bipyridine/bis-pyrimidinethiolate Co( <scp>iii</scp> ) complex covalently immobilized onto MoS <sub>2</sub> nanosheets
The development of an oxygen evolution reaction (OER) electrocatalyst based on 2H-MoS<sub>2</sub> nanosheets bearing covalently linked octahedral tris-chelating bipyridine/bis-pyrimidinethiolate Co(III) complexes as catalytic centers is presented. The nanohybrid material exhibits superior OER electroactivity and facilitates electron flow, compared to 2H-MoS<sub>2</sub>, which is attributed to the dispersed, surface-located molecular Co(III) catalytic centers and supported by a catalytic cycle for water oxidation that proceeds through a single-site water nucleophilic attack mechanism, operating within the Co(III)/Co(IV) redox manifold.
