摘要

The emerging solar desalination by interfacial evaporation shows great potential for alleviating the global freshwater crisis. However, salt deposition on the whole evaporation surface during steam generation leads to a deterioration in the evaporation rate and long-term stability. Herein, it is demonstrated that a hydrogel-based 3D structure can serve as an efficient and stable solar evaporator by salt localized crystallization for high-salinity brine desalination. Under the function of micron-grade brine transport management and edge-preferential crystallization promoted by this novel design, this 3D hydrogel evaporator exhibits a superior salt-resistant property without salt deposition on the photothermal surface even in 20 wt% brine for continuous 24-h illumination. Moreover, by virtue of the synergistic effect of the promising 3D structure and excellent water transport of hydrogel, the proposed evaporator possesses an excellent evaporation performance achieving 2.07 kg m(-2) h(-1) on average in a high-salinity brine (from 10 to 25 wt% NaCl) under 1 sun irradiation, among the best values reported in the literature. With stable and efficient evaporation performance out of high-salinity brine, this design holds great potential for its applications in sustainable solar desalination.
