Solar-driven interfacial water evaporation is a potential solution for wastewater treatment, but challenges remain in comprehensive water purification and dealing with high pollutant concentrations. This review evaluates optimization strategies, discusses photothermal materials and purification strategies, and addresses the challenges of practical implementation of interfacial water evaporation in wastewater treatment.
Solar-driven interfacial water evaporation has received considerable attention as a potential solution for wastewater treatment applications. Despite previous studies confirming significant performance improvements through rational solar evaporator design, challenges remain in achieving comprehensive condensed water purification and addressing high pollutant concentrations in source water. In this review, we evaluate the optimization strategies for solar absorption, thermal management, and water-existing forms to achieve highefficiency water evaporation. In addition, we provide a brief overview of photothermal materials that are based on a variety of different photothermal conversion mechanisms. Based on previous research, our focus is on exploring purification strategies using interfacial water evaporation technology to address common water pollutants, including volatile organic compounds, dyes, metal ions, and more. Lastly, we discuss the challenges of practical implementation of interfacial water evaporation technology in the field of wastewater treatment, followed by our views and future perspectives.
