Abstract Solar‐driven interfacial evaporation toward highly salinity brine has drawn great attention due to its distinct advantages. Generally, most studies focus on how improve the water rate while restrain salt accumulation evaporators. In fact, generating/recycling during process is of equal importance since also valuable. However, realize high generation keep still a challenge, high‐efficiency and conflicting in cases. Herein, both formation have been achieved via surface engineering 3D evaporator: 1) Constructing surround‐Janus structure with different wettability around evaporator; 2) Enhancing crystallization introduction tapes special surface. Thanks engineering, (20 wt%) can reach up ≈2.8 kg m −2 h −1 , be as ≈0.1 . Moreover, performance well maintained even when evaporator irradiated angles. Specially, proof concept, potential for Li + /Na separation demonstrated.

Abstract Solar-powered interfacial evaporation is an energy-efficient solution for water scarcity. It requires solar absorbers to facilitate upward transport and limit the heat surface efficient evaporation. Furthermore, downward salt ion also desired prevent accumulation. However, achieving simultaneously fast uptake, transport, localization challenging due highly coupled water, mass, thermal transport. Here, we develop a structurally graded aerogel inspired by tree systems collectively optimize salt, The arched features root-like, fan-shaped microchannels rapid uptake diffusion, horizontally aligned pores near through maximizing absorption minimizing conductive loss. These structural characteristics gave rise consistent rates of 2.09 kg m −2 h −1 under one-sun illumination in 3.5 wt% NaCl 7 days without degradation. Even high-salinity 20 NaCl, maintained stable at 1.94 8 crystal formation. This work offers novel microstructural design address complex interplay
