Electronic Structure Regulation of Fe sites by Coordinating Moieties in the Fenton-like Process Enables Tunable Water Decontamination

The electronic configuration modulation of active sites is critical to control the catalytic mechanism in the Fenton-like process as it offers a promising strategy for tunable water decontamination. Herein, electronic density-dependent catalysts based on FeOCl with externally coordinated moieties were fabricated to fulfill the switching of the catalytic oxidation mechanism in peroxymonosulfate (PMS)-based Fenton-like reactions. The experimental results indicate that the catalytic activity and reaction mechanism vary with the changes in electronic density around the Fe site, which determines the contributions of radical and nonradical mechanisms, thus achieving selective or nonselective oxidation.
