Abstract Using solar energy to drive seawater desalination via steam generation (SSG) is a sustainable strategy for clean water supply. The weak efficiency and poor durability due salt deposition severely restrict practical SSG operation. Traditional evaporators are difficult simultaneously guarantee efficient evaporation long‐term rejection increased salinity. Herein, tackle this dilemma, thermal gradient fabric (TGF) evaporator with an auxiliary active field constructed. Different from traditional works where additional resources improved rate exacerbate accumulation, the well integrated external boost ion circulation through moderate Marangoni flow, leading continuous superior utilization under high‐salinity desalination. accelerated (2.42 kg m −2 h −1 ) resistance (30 days of in 10 wt.% brine) achieved optimized construction.

Abstract Interfacial solar evaporation offers a green and sustainable solution to solve clean water shortages via solar‐driven desalination. However, salt crystallization accumulation on evaporators have become the primary hindrances long‐term practical application of interfacial technology. To tackle this challenge, photothermal evaporator with novel parallel two‐water paths strategy is developed in study. Unlike conventional one‐way path, which generally leads at supply end surfaces, thereby limiting lifespan compromising performance, here, second ion diffusion distribution within reconfigured optimized. No occurs either surfaces or paths, eliminating impact performance enabling convenient collection. A high stable rate 3.09–3.26 kg m −2 h −1 recorded over 84 continuous NaCl (3.5 wt.%) without evaporator, making it an ideal for zero liquid discharge evaporation.
