Abstract

Abstract

En 中文
• Atomic-level modulation of Fe3+−NC−M2+ units dictates the competitive kinetics of radical and non-radical pathways. • Ni-induced spin-state transitions lower activation barriers, promoting 1O2 selectivity (56.2%) and intramolecular PMS disproportionation. • The NiFe-PBA catalyst achieves a 0.061 min-1 degradation rate, a three-fold enhancement over homonuclear FeFe-PBAs. • Rapid intervalence charge transfer drives PMS disproportionation, ensuring high TOC removal and pH-adaptive stability.
