In subsurface environments, Fe(II)-bearing clay minerals can serve as crucial electron sources for O2 activation, leading to the sequential production of O2•–, H2O2, and •OH. However, observed •OH yields are notably low, underlying mechanism remains unclear. this study, we investigated oxidants from oxygenation reduced Fe-rich nontronite NAu-2 Fe-poor montmorillonite SWy-3. Our results indicated that dependent on mineral Fe(II) species, with edge-surface exhibiting significantly lower compared those interior Fe(II). Evidence in situ Raman Mössbauer spectra chemical probe experiments substantiated formation structural Fe(IV). Modeling elucidate pathways Fe(IV) respectively consume 85.9–97.0 14.1–3.0% electrons H2O2 decomposition during oxygenation, Fe(II)edge/Fe(II)total ratio varying 10 90%. Consequently, these findings provide novel insights into low different minerals. Since selectively degrade contaminants (e.g., phenol), generation should be taken consideration carefully when assessing natural attenuation redox-fluctuating environments.
