Utilizing solar steam generation to treat seawater and sewage, as an emerging and effective technology, can obtain clean water. There is an abundance of water demand and a shortage of water supply in the world today. Herein, we demonstrate an integrated evaporator of boron nanosheets modified with molybdenum disulfide (MoS₂) as a photothermal materials and a konjac glucomannan (KGM) sponge with excellent pore structure as a thermal insulator and water supplier for solar clean water generation. A rapid evaporation rate (1.538 kg m⁻² h^-1) and high solar evaporation efficiency (96.5 %) under 1-sun radiation (1 kW m⁻²) can be achieved in the two-dimensional structure system. This work provides a new way to design and manufacture renewable solar steam generation for water purification.

利用太阳能产生的蒸汽来处理海水和污水是一种新兴的有效技术，它可以获得清洁的水。当今世界，水的需求量很大，而水的供应却短缺。在本文中，我们演示了用二硫化钼（MoS ₂）改性的硼纳米片作为光热材料的集成蒸发器，以及具有优异孔结构的魔芋葡甘露聚糖（KGM）海绵作为绝热剂和太阳能清洁水的水供应商。在1个太阳辐射（1 kW m ^-2）下快速蒸发速率（1.538 kg m ^-2 h ^-1）和高太阳蒸发效率（96.5％））可以在二维结构系统中实现。这项工作为设计和制造用于水净化的可再生太阳能蒸汽产生提供了新途径。
