Aeration accounts for 35–51% of the overall energy consumption in wastewater treatment processes and results an annual 5–7.5 billion kWh. Herein, a solar-powered continuous-flow device was designed aeration-free situ Fenton-like reactions to treat wastewater. This system is based on combination TiO2–x/W18O49 featuring heterophase oxygen vacancy interactions with floating reduced graphene/polyurethane foam, which produces hydrogen peroxide at rates up 4.2 ppm h–1 degradation more than 90% various antibiotics. The vacancies play important role stretching O–O bond by regulating d-band center TiO2–x/W18O49, promoting hydrogenation *·O2– or *OOH H+ enrichment, accelerating production reactive species spontaneous adsorption peroxide. Furthermore, mechanisms antibiotics actual were thoroughly investigated. In short, study provides meaningful reference potentially undertaking "aeration-free" Fenton reaction, can help reduce even completely eradicate aeration costs requirements during
