“…Deutscher et al [12] revealed that introducing sulfur ligands to replace two equatorial nitrogen ligands weakens the Fe=O bond and thus enhances the oxidative reactivity of the Fe IV =O unit. In our former research, [13] MoS 2 was considered as an optional inorganic host material. Fe dopants induce the transition from the thermodynamically stable 2H phase with trigonal prismatic coordination to the metastable octahedral coordinated 1T MoS 2 .…”

Oxoiron(IV) species are a critical intermediate in the Fe‐based Fenton‐like process at circumneutral pH, and its oxidative reactivity is closely related to the ligands. An optional inorganic host material, MoS2, is selected to construct a highly reactive sulfur ligand coordinated Fe species in this work. The Fe species doped in MoS2 is presented as the FeII centre and triggers the transformation of the 2H phase to the octahedral 1T phase MoS2. The role of the interaction between doped Fe and the MoS2 host lattice on the formation of oxoiron(IV) is studied. A significant Fenton‐like reactivity and a remarkable accumulation of oxoiron(IV) species were observed for Fe‐MoS2. The quenching experiment was implemented to disclose the predominant role of oxoiron(IV) species in the Fe‐MoS2/H2O2 Fenton‐like system. Furthermore, oxoiron(IV) species could transform into the ⋅O2− and 1O2, which further expedites the Fenton‐like reaction.
