Localized solar photothermal heating via plasmonic interfaces for high-efficiency water evaporation Photothermal conversion for interfacial solar water evaporation is a promising green energy technology for effective wastewater purification. In the current work, we report the fabrication of a novel interfacial evaporator system based on plasmonic nanoparticles (X-NPs = Ag, Ni, Co, and Cu) as efficient photothermal conversion agents, supported on a microporous Whatman membrane (MPM).
