Solar steam generation, utilizing abundant solar energy and floating photothermal materials, has been considered as one of the most sustainable, efficient ways to solve the problem of water shortage. Here, a new system for solar steam generation is fabricated based on a PEGylated MoS₂-cotton cloth (PMoS₂-CC). 80.5–90 ± 3.5% of high-efficiency solar steam generation is achieved under a light density of 1–5 kW m^–2 because of the good gas permeability of CC and the hydrophilic property of PMoS₂-CC. The self-growth PMoS₂-CC provides good photothermal performances in pure water and saline water. The water evaporation rate with PMoS₂-CC keeps a stable value after a long-time illumination (4 h) and 32 times cycle tests. Our result provides a way to prepare pure water in the applications for alleviating a scarcity of drinking water.

棉布基质上的聚乙二醇化自生长MoS ₂，用于高效利用太阳能

利用丰富的太阳能和漂浮的光热材料来产生太阳能蒸汽，已被认为是解决缺水问题的最可持续，最有效的方法之一。在此，基于聚乙二醇化的MoS _2-棉布（PMoS ₂ -CC ）制造了一种新的太阳能发电系统。由于CC的良好气体渗透性和PMoS ₂ -CC的亲水性，在1–5 kW m ^–2的光密度下可实现80.5–90±3.5％的高效太阳能蒸汽产生。自增长的PMoS ₂ -CC在纯水和盐水中具有良好的光热性能。PMoS ₂的水蒸发速率-CC经过长时间照明（4小时）和32次循环测试后保持稳定值。我们的结果提供了一种在减轻饮用水短缺的应用中制备纯净水的方法。
