A high-efficient and salt-rejecting 2D film for photothermal evaporation

open access: yesiScience, 2023
Summary: The solar-driven desalination is seen as a sustainable way to combat water scarcity. However, the solar steam generation efficiency has long been restricted by the high vaporization enthalpy of water and low energy density of natural sunlight ...
