Abstract
This paper presents a self-cyclable system coupling solar light-assisted H₂O₂ production from water and photo-Fenton-like reactions using an artificial leaf. It achieves an unassisted H₂O₂ production rate of 0.77 µmol/(min·cm²) under 1 Sun AM 1.5 illumination, with a solar-to-hydrogen peroxide efficiency (SHyE) of 1.46%. A larger artificial leaf (70 cm²) was used for wastewater purification, requiring only water, oxygen, and sunlight. The system demonstrates the feasibility and scalability of photoelectrochemical technology for decentralized environmental applications.
