Owing to its high conversion efficiency of solar energy and transformative industrial potential, solar-driven interfacial evaporation has been proposed as a promising alternative to conventional bulk heating-based evaporation, potentially reducing thermal losses and improving energy conversion efficiency. Firstly, by using the process of plant transpiration, we developed here the nanogenerator made of multi-walled carbon nanotubes-coated cellulose paper-located on polystyrene foam that can float on water surfaces with high electricity generation and excellent freshwater production in water-rich locations such as lakes, rivers, and oceans at all hours of the day. Secondly, a highly charged solar evaporator for in-situ freshwater and power generation developed by a UV-induced deposition of Fe3O4@polypyrrole nanospheres anchored on a self-floating cellulose evaporator. This work will further insight into further advancement in the multifunctional integration of solar evaporation technology concerning the water-energy nexus.
