Emerging solar interfacial evaporation offers the most promising response to severe freshwater crisis. However, challenging bottleneck is conflict between resisting salt accumulation and maintaining high performance since conventional salt-resistant evaporators enhance water flow remove salt, leading tremendous heat loss. Herein, an ion-transfer engineering proposed via a Janus ion-selective hydrogel that enables ion-electromigration removal, breaking historical dependence on convection, significantly lowering The hydrogels drive cations downward anions upward, away from surfaces. An electrical potential thus established inside evaporator in 15 wt% brine removed stably for seven days. A record-high rate of 6.86 kg m-2 h-1 brine, 2.5 times previously reported works, achieved. With from-scratch route, comprehensive water-thermal analysis, performance, this work holds great future evaporators.

Abstract Solar desalination is a promising strategy to utilize solar energy purify saline water. However, the accumulation of salt on evaporator surface severely reduces light absorption and evaporation performance. Herein, simple eco‐friendly method fabricate 3D gradient graphene spiral sponge (GGS sponge) presented that enables high‐rate zero liquid discharge (ZLD) high‐salinity brine. The structure GGS enhances recovery, while network structures facilitate radial brine transport directional crystallization, which cooperate endow with superior (6.5 kg m −2 h −1 for 20 wt.% brine), efficient collection (1.5 ZLD desalination, long‐term durability (continuous 144 in brine).

Freshwater scarcity and microplastics (MPs) pollution are two concerning intertwined global challenges. In this work, we propose a "one stone kills birds" strategy by employing an interfacial solar evaporation platform (ISEP) combined with MPs adsorbent. This aims to produce clean water simultaneously enhance removal. Unlike traditional predecessors, our ISEP generates condensed free from contamination. Additionally, the photothermally driven separation process significantly improves removal performance. We observed ratio increase of up 5.5 times compared previously reported adsorbents. Thus, rationally-designed holds promising potential not only mitigate existing issue but also remediate in natural environments.

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.
