Abstract Double‐reaction‐centers (DRCs) Fenton‐like chemistry with low or zero oxidant addition has garnered increasing attentions due to their alignment the principles of green and sustainable development. However, regulation such processes remains a significant challenge, primarily deficiencies in microscopic interpretation electron migration mechanisms operating addition. In this work, iron single‐atom DRCs catalyst (Fe/N‐SAC) was prepared for internal‐driven system (zero addition) external‐driven (low peroxymonosulfate [PMS] addition). Results indicated absence dissolved oxygen activation PMS‐zreo Fe/N‐SAC system, single atoms acted as predominate acceptors extract electrons from electron‐donating pollutants valence decreasing +2.37 +2.07 they could also be recovered under O 2 atmosphere. contrast, transferred both PMS Fe/N‐SAC/PMS involving predominant transfer process (ETP) internal‐driven. Furthermore, two experimental devices based on core systems were designed achieve long‐term operation. These studies will complement catalytic module applications systems.
