Seawater Desalination by Interfacial Solar Vapor Generation Method Using Plasmonic Heating Nanocomposites.

摘要: With the ever-growing demand in fresh water supply, great efforts have been devoted to developing sustainable systems which could generate continuously. Solar vapor generation is one of promising strategies comprise an unlimited energy source and efficient solar-to-heat generators for overcoming scarcity. However, current solar suffer either from inefficient utilization or expensive fabrication process. In this paper, we introduced a nano-plasmonic approach, i.e., floatable nanocompoiste where copper sulfide nanorods (Cu2-xS NRs) are embedded polyvinyl alcohol (PVA) matrix, solar-to-vapor generation. A high efficiency ~87% evaporation rate 1.270 kg m-2 h-1 were achieved under simulated irradiation 1 sun. illumination natural daylight, seawater was purified using Cu2-xS NRs-PVA gel, with purity, as distilled drinking water. The plasmonic nanocomposites demonstrated here easy fabricate highly generation, illustrating potential solution future desalination.
