Dynamic electronic modulation of single-atom Fe sites with p-block metal coordination enables highly selective generation of Fe^IV = O in Fenton-like reactions.

ABSTRACT: High-valent iron-oxo species (Fe^IV=O) have garnered increasing attention for water purification, while the selective generation of Fe^IV = O in Fenton-like reactions still lacks an effective control protocol at the atomic level. Here, we propose an innovative coordination strategy to develop a series of diatomic FeM_p-N-C catalysts with p-block metals (M_p: Bi, In, and Sb) for improving the selectivity of Fe^IV = O generation via peroxymonosulfate (PMS) activation. The p-block metal coordination facilitates the chemical bonding with the terminal hydroxyl oxygen of PMS to construct an electron-rich microenvironment surrounding the Fe active center, thereby transferring twice as many electrons to enable Fe^IV = O production through
