Abstract

Solar desalination is a promising solution to address global water scarcity. In this study, a novel superhydrophobic photothermal evaporator based on MoS₂ nanoflowers, known for their excellent photothermal conversion properties, was developed. The evaporator is coated with 1H, 1H, 2H, 2H-Perfluorodecyltriethoxysilane (PFDTES) to create superhydrophobic structures, which are then loaded onto a macroporous non-woven fabric (NWF) to facilitate efficient steam release. The hydrophobic PFDTES coating effectively prevents salt crystallization, ensuring long-term desalination. The developed device demonstrates an exceptional solar steam generation performance of 1.52 kg m⁻² h⁻¹ with an evaporation efficiency of up to 87.1 %. This evaporator offers a promising solution to water scarcity challenges due to its high evaporation efficiency, impressive durability, and low-cost.

基于 MoS2 纳米流的超疏水光热蒸发器，用于高效太阳能海水淡化

太阳能海水淡化是解决全球缺水问题的一个前景广阔的方案。本研究开发了一种基于 MoS2 纳米花的新型超疏水光热蒸发器，该蒸发器以其优异的光热转换性能而著称。该蒸发器涂有 1H、1H、2H、2H-全氟癸基三乙氧基硅烷（PFDTES），以形成超疏水结构，然后将其装载到大孔无纺布（NWF）上，以促进蒸汽的有效释放。疏水性 PFDTES 涂层可有效防止盐结晶，确保长期脱盐。所开发的设备具有 1.52 kg m-2 h-1 的出色太阳能蒸汽生成性能，蒸发效率高达 87.1%。这种蒸发器蒸发效率高、经久耐用且成本低廉，为解决缺水问题提供了一个前景广阔的解决方案。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
