Abstract

seawater desalination is an important strategy to give clean sources for water treatment by solar evaporators to produce heat from the solar in recent years. Herein, for solar steam generation, we prepare MIL-125 mixed with polyurethane foam (MPU). We improved MPU by using graphene oxide to enhance the evaporation rate. Polyurethane foam has various advantage such as floating property and self-pump water by its hydrophilic structure The porosity property of the fabricated polyurethane foam was noticed in the SEM images which include the hydrophilic nature and the open porous of the fabricated Polyurethane foam. MIL-125 has large salt rejection, and large water permeability. GO enhanced solar absorption, and photo-thermal conversion efficiency since it exhibits broad band light for steam generation uses. Under one solar irradiation, the mass change of water by GO@MIL-125 (MG) nanocomposite (0.62 kg m−2) is larger than MIL-125 (0.44 kg m−2) (M). Additionally, the evaporators exhibit organic dye removal from contaminated water and produces pure condensed freshwater.
