Spontaneous FeIII/FeII redox cycling in single-atom catalysts: Conjugation effect and electron delocalization

open access: yesiScience, 2023
Summary: The mechanism of spontaneous FeIII/FeII redox cycling in iron-centered single-atom catalysts (I-SACs) is often overlooked. Consequently, pathways for continuous SO4·-/HO⋅ generation during peroxymonosulfate (PMS) activation by I-SACs remain ...
