Interfacial solar vapor electrolyzer for efficient and durable hydrogen production directly from seawater.

ABSTRACT: Solar-powered water splitting from seawater offers a sustainable pathway for hydrogen production, yet current methods are challenged by the complex composition of seawater, as well as intrinsic thermodynamic and kinetic limits when using liquid water as reactants. This work proposes an interfacial solar vapor electrolyzer (ISVE), which synergistically utilizes interfacial vapor generation driven by dissipated solar-thermal energy and solar-powered electricity to enable efficient and stable hydrogen (H₂) production directly from seawater. Abundant solar-thermal vapor as the reactant during electrolysis not only significantly enhances durability due to intrinsically purified properties, but also fundamentally increases the solar-to-hydrogen (STH) efficiency owing to reduced thermo
