Iron Single‐Atom Based Double‐Reaction‐Center Catalysis Triggers Internal‐Driven and External‐Driven Pathways for Green Fenton‐Like Chemistry

Angewandte Chemie International Edition, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

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 O2 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.

Synchronization Strategy for Activity and Stability in Fenton‐Like Single‐Atom Catalysis

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: May 2, 2025

Abstract Single‐atom catalysts (SACs) have garnered significant attention in the applications of environmental remediation based on Fenton‐like systems. Current research single‐atom catalysis often emphasizes catalytic activity and mechanism regulation, while paying limited to simultaneous enhancement both stability—a critical factor for practical scale‐up SACs. This review systematically summarizes recent advances synchronization strategies improving stability catalysis, with a focus design principles mechanisms four key strategies: coordination engineering, confinement effects, carrier substitution, module design. To best knowledge, this represents first comprehensive from perspective concurrent optimization stability. Additionally, auxiliary role machine learning lifecycle assessment (LCA) is evaluated advancing these strategies. By investigating interplay among different support materials, configurations, reaction environments, as well enlarged modules, factors governing stability/activity SACs are highlighted, future directions proposed developing next‐generation high efficiency long‐term durability remediation.
