Abstract Solar‐driven interfacial evaporation (SIE) utilizes solar energy at the air/liquid interface, offering an energy‐efficient alternative to conventional methods. Due strong hydrogen bonding between water molecules, requires breaking these intermolecular hydrogen‐bond networks, which demand a large amount of energy. As result, achieving efficient remains technological challenge. This study presents novel approach that uses superoxide radicals (·O₂ − ) disrupt network and enhance rates. A composite heterostructure reduced graphene oxide (rGO) oxygen vacancy (Ov)‐doped gadolinium (rGO@Ov‐Gd₂O₃) is developed explore this mechanism. Gd₂O₃ with vacancies generates ·O₂ under light irradiation. Compared rGO framework, rate rGO@Ov‐Gd₂O₃ enhanced by 60%, reaching 4.03 kg/(m 2 ·h). Molecular dynamics (MD) simulations density functional theory (DFT) calculations confirm enhancement results from disruption weakening . work highlights potential improve efficiency demonstrates their broader applicability in organic dye degradation brine purification, showcasing value solar‐driven photothermal systems.
