Abstract
Solar-powered interfacial evaporation is an emerging solar energy harvesting technology developed to address the global energy crisis and freshwater shortage. However, non-directionally flowing water inevitably acts as a medium for top–down heat transfer via thermal convection, resulting in a poor evaporation performance. Herein, a fully biomass-based bilayer multifunctional solar evaporator consists of an upper lignin-derived porous carbon (LPC)-embedded chitosan/lignin (CSL) composite aerogel layer featuring vertically small channels and an underlying hydrophilic CS aerogel. The photothermal and evaporation capabilities of the top layer, combined with enhanced capillary forces, drive efficient evaporation.…
