Controlling the Co–S coordination environment in Co-doped WS<sub>2</sub> nanosheets for electrochemical oxygen reduction
Wei Hong, Erika Meza, Christina Li
Abstract
The impact of Co–S coordination environment in pH 7 ORR catalysis is evaluated using dilute Co atoms adsorbed on WS 2 nanosheets. Optimal reactivity is achieved when Co is coordinated to both sulfur atoms on WS 2 and labile solvent ligands.
