Abstract
Abstract Facing the global water shortage challenge, solar‐driven desalination is considered a sustainable technology to obtain freshwater from seawater. However, the trade‐off between the salt cycle and heat localization of existing solar evaporators (SE) hinders its further practical applications. Here, inspired by water hyacinth, a self‐standing and self‐floating 3D SE with adiabatic foam particles and aligned water channels is built through a continuous directional freeze‐casting technique. With the help of the heat insulation effect of foam particles and the efficient water transport of aligned water channels, this new SE can cut off the heat transfer from the top photothermal area to the bulk water…
