Highly Stable Electrosynthesis of Hydrogen Peroxide Adapted to Fluctuating Renewable Energy

, the system sustains over 55 stable start-stop cycles with an average Faradic efficiency above 96%. The high selectivity and durability are attributed to the reservoir-containing O-coordinated Co single-atom sites and the self-healing capability of gas diffusion electrodes. Furthermore, we evaluate its practicality under simulated photovoltaic power supply scenarios in the field of smart agriculture, particularly for integrated fertilization, disinfection, and irrigation. By addressing the variability of renewable energy and optimizing the integration of electrochemical processes, our work paves the way for fully realizing green electrification in sustainable chemical synthesis.
