A Porous Interfacial Photothermal Layer of Fused Core–Shell Carbon‐Polymer Nanospheres for Directional Salt Crystallization and Zero‐Liquid‐Discharge

Advanced Materials, EarlyView.
A hierarchical hydrogel evaporator with a thin, porous photothermal layer of fused core–shell carbon‐polymer nanospheres enables ultrafast interfacial solar evaporation with minimized heat loss and sufficient water supply. Directional advection‐dominated brine transport, coupled with Marangoni‐driven interfacial flow, drives salt away from the active ...
