Effect of FeCo2S4 on electrocatalytic I3− reduction: Theoretical and experimental aspects

The design and preparation of alternative noble metal catalysts play a crucial role in energy conversion and storage fields. Herein, FeCo2S4 was designed and synthesized for electrocatalytic reduction from I3− to I− and the mirror-like FeCo2S4 displayed excellent chemical, thermal and mechanical stability. The adsorption energy of I3− ions adsorbed on the surface of (3 1 1), (4 2 2) and (4 4 0) were calculated by the density functional theory...
