Description
Summary:Utilizing sunlight to accelerate water evaporation is emerging as a promising strategy for desalination and for distilling wastewater. Here we report on the application of ferric tannate as such a photothermal material, which is deposited onto a polyvinylidene fluoride (PVDF) membrane and encapsulated with titanium dioxide via atomic layer deposition. This system achieves 63.9% efficiency for the overall process, suggesting strong potential for real-world application. Ferric tannate is used as a photothermal material and integrated with a polymer membrane by atomic layer deposition for solar water distillation.
