Sulfidized nanoscale zerovalent iron (SNZVI) is a promising material for groundwater remediation. However, the relationships between sulfur content and speciation properties of SNZVI materials are unknown, preventing rational design. Here, effects on crystalline structure, hydrophobicity, speciation, corrosion potential, electron transfer resistance determined. Sulfur incorporation extended nano-Fe0 BCC lattice parameter, reduced Fe local vacancies, lowered to transfer. Impacts main species (FeS FeS2 ) hydrophobicity (water contact angles) consistent with density functional theory calculations these FeSx phases. These well explain reactivity selectivity during reductive dechlorination trichloroethylene (TCE), hydrophobic contaminant. Controlling amount in made it highly reactive (up 0.41 L m-2 d-1 selective TCE degradation over water 240 moles per mole H2 O), an efficiency up 70%, values 54-fold, 98-fold, 160-fold higher than NZVI, respectively. findings can guide design robust tailored specific application scenarios.
