The activity of electrocatalysts strongly depends on the number active sites, which can be increased by downsizing electrocatalysts. Single‐atom catalysts have attracted special attention due to atomic‐scale sites. However, it is a huge challenge obtain CoO x catalysts. Co‐based metal–organic frameworks (MOFs) own atomically dispersed Co ions, motivates design possible pathway partially on‐site transform these ions species, while reserving highly porous features MOFs. In this work, for first time, targeted formation species realized in ZIF‐67 O 2 plasma. abundant pores provide channels plasma activate MOFs produce act as sites catalyze oxygen evolution reaction with an even better than RuO .
