O_2 evolution electrocatalysis: Electronic, atomic, and nanoscale dynamics matter

摘要

InNature, Mefford, Chueh, and colleagues describe how they investigated the oxygen evolution reaction (OER)in situat sub-micrometer resolution. Nanoscale variations of current density, geometry, and oxidation states show that the currently emerging and potentially paradigm-shifting picture of redox-active, structurally dynamic catalyst materials might need to include the nanoscale.
