Zusammenfassung: | 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. |
