Oxygen Evolution Reaction: Elevating the d‐Band Center of Six‐Coordinated Octahedrons in Co₉S₈ through Fe‐Incorporated Topochemical Deintercalation (Adv. Energy Mater. 5/2021)

In article number 2003023, Wenwu Zhong and co-workers re-design the six-coordinate octahedrons in Co9S8 utilizing an Fe-incorporated topochemical deintercalation method to optimize the electrocatalytic activity for the oxygen evolution reaction (OER). This work sheds lights on the design of OER catalysts through polyhedron engineering using topochemical deintercalation.
