Hydrogel as a solar evaporator shows great potential in freshwater production. However, hydrogels often lead to an imbalance between energy input and water supply management due their excessively high saturated content. Thus, achieving stable water-energy-balance hydrogel evaporators remains challenging. Here, by tortuosity engineering designed transport channels, seamless high-tortuosity/low-tortuosity/high-tortuosity structured (SHLH structure hydrogel) is developed, which enables the with customized rate, leading controlled at interface. An excellent equilibrium photothermal conversion established, maximum utilization of realized, thereby evaporation rate 3.64 kg m

An Extremely Salt‐Resistant Hydrogel‐Based Solar Evaporator for Stable Saturated Brine Desalination

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

Abstract Hydrogel‐based solar evaporators are widely concerned because of their excellent evaporation performance due to the “water activation” effect by reducing enthalpy. However, current challenge is trade‐off between a high rate and salt tolerance. Here, 3D chitosan‐based hydrogel evaporator with directional vertical channel structure using one‐pot in situ strategy freezing method, innovatively designed. Owing its structure, ions can quickly return, while steam overflow without obstruction, allowing achieve exceptional resistance, simultaneously. Consequently, an extremely salt‐resistant system achieved, even saturated brine (salinity 26.47 wt.%), no crystals accumulating after continuous over 8 h 2.83 kg m −2 −1 under one sun illumination. This best reported hydrogel‐based system. With record‐high this work improves practicality for high‐salinity desalination.

Опубликована: Апрель 30, 2025

The growing global freshwater shortage and climate crisis are increasing the dependence on water desalination technologies. To meet this pressing demand, innovative solutions that utilize renewable energy sources like solar power, with an emphasis improving evaporation processes, essential. Although considerable research has been conducted a variety of materials structural designs, development highly efficient steam generators for large-scale use remains challenge. Here, we introduce novel design: two-layer vertical cylinder in roll format integrates small, inverted cone-shaped pure copper (ICPC) foam etched foil to enhance thermal management. primary objective is advance direct interfacial by effectively capturing both reflected light while preventing salt accumulation through self-cleaning. This design leverages optical properties three materials─absorption, reflection, transmission─while providing deeper insights into seawater behavior within foam's interconnected pores. It also addresses common challenges encountered traditional evaporators, such as buildup, uncontrolled flow, poor cutting-edge system exhibits exceptional performance, remarkable adaptability diverse configurations, represents breakthrough sustainable chemistry, featuring advanced engineering achieves outstanding rate 17.15 kg·m-2·h-1 under 1 sun irradiation.
