Abstract
An evaporator for solar desalination and a preparation method thereof and use thereof are provided. The evaporator has a porous skeleton, interconnected channels, and a hydrophobic decoration. The interconnected channels are formed from gaps of the porous skeleton, and the hydrophobic decoration is positioned on the surface of the porous skeleton. The evaporator is for sustainable solar water evaporation even in highly salty water. Specifically, the continuous evaporation for 24 h without salt precipitation in 20 wt % NaCl solution can be realized.
