Boosting the oxygen evolution reaction performance of CoS2 microspheres by subtle ionic liquid modification

Hierarchical CoS2 microspheres were prepared and modified with a cationic ionic liquid (IL). The composite shows enhanced oxygen evolution reaction (OER) performances attributed to the fact that the OER equilibrium is driven forward by the IL, according to Le Chatelier's principle, and by the e...

Description
Summary:Hierarchical CoS2 microspheres were prepared and modified with a cationic ionic liquid (IL). The composite shows enhanced oxygen evolution reaction (OER) performances attributed to the fact that the OER equilibrium is driven forward by the IL, according to Le Chatelier's principle, and by the electrostatic affinity generated at the CoS2/electrolyte interface.
