Self-sustaining charge circulation in the FeS2/MoS2 heterostructure. (IMAGE)
Caption
Schematic illustration of the FeS2/MoS2 catalytic interface, where a built-in electric field drives directional electron transfer between dual active sites. In this system, Fe-associated sites favor electron extraction to activate peroxymonosulfate and generate radical species, while Mo-associated sites support electron injection and the complementary reactive oxygen species formation. This self-sustaining charge-circulation loop enables continuous active-site regeneration, synergistic radical/non-radical oxidation, and efficient micropollutant removal.
