Hollow RuSe 2 ‐MoSe 2 @NC Microsphere/Chitosan Aerogel Janus Electrode for Solar‐Driven Photothermal‐Promoted Synchronous Seawater Splitting and Evaporation

with 92% photothermal efficiency. In this work, the solar-driven photothermal effect is utilized to innovatively achieve synchronous seawater splitting and evaporation on a single electrode. Additionally, a coupled photothermal device designed for synergistic seawater electrolysis and evaporation is successfully operated under natural sunlight.
