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

Environmental pollution and sewage surges necessitate effective water purification methods. Solar interfacial evaporation offers a promising solution, which needs advancements in salt resistance, efficiency, stability. Herein, inspired by the structure of wood, unidirectional freeze-drying method was used to develop vertically aligned channels antioil-fouling poly(vinyl alcohol)-CNTs-waste carton fiber@polydopamine (PVA-CNTs-WCF@PDA) aerogel for desalination wastewater treatment. The anisotropic three-dimensional porous enables it rapidly transport interface resist deposition. Meanwhile, its unique is combined with CNTs PDAs excellent broadband spectral absorption capacity because composite aerogels can interact molecules reduce their vaporization enthalpy. shows an photothermal rate (2.626 kg m-2 h-1) efficiency (94.24%) under one-sun irradiation. Additionally, evaporator conduct 10 consecutive evaporations 3.5% brine, indicating that has ability desalination. Finally, also purify oil-in-water emulsion mine wastewater.
