| Zusammenfassung: | © 2020 Wiley-VCH GmbH. Solar vapor generation is a promising method to efficiently produce fresh water. However, the insufficient vapor yields under natural daylight restrict its practical applications, and the basic evaporation mechanisms are deficient for reasonable design of evaporator structure. Here, hydrophobic nano-confined water molecule channels (NCWMCs) are demonstrated, which can reduce the vaporization enthalpy for water evaporation and achieve a record vapor generation rate of 1.25 kg m-2 h-1 under 0.5 sun irradiation. Molecular dynamics simulations reveal the cluster-evaporation process in the NCWMC system. As a result, the evaporator with NCWMC system can effectively purify seawater and wastewater samples using this environmentally friendly strategy |
