The marine iron cycle is fast and dynamic, partly fueled by vast particulate iron inputs, but the mechanisms that activate this reservoir remain unresolved. This study shows that mineral photocatalysis provides an important abiotic pathway for Fe(II) production in sunlit waters.
Laboratory experiments using synthetic iron oxides and anatase in artificial seawater demonstrate that anatase (TiO2) drives rapid Fe(III)-to-Fe(II) cycling at rates up to fourfold higher than current model assumptions. The study proposes that mineral photocatalysis helps explain the persistence of Fe(II) in sunlit waters as a high-flux steady state of photochemical production coupled with biological uptake. These findings establish mineral photocatalysis as a key driver in the ocean iron cycle and suggest that bioavailable iron fluxes from particles have been underestimated.
