3D Biomass‐Based Interfacial Solar Steam Generation: Component, Optimization, and Application

Abstract

The seawater desalination and wastewater treatment by the interfacial solar steam generation (ISSG) technique is considered as a green, economical, sustainable, low‐energy‐consumption, and potential fresh water production strategy to solve the water shortage and energy crisis. Recently, efficient biomass‐based ISSGs (BISSGs) have been widely reported due to its efficient photothermal conversion efficiency and good hydrophilic performance. The BISSGs with efficient solar absorption and water transmission performance by design and optimization their various forms and structures and related photothermal properties is also significantly great for its scale application. This review highlights recent advancements in 3D BISSG systems, with a focus on the design and optimization of photothermal conversion materials and substrate materials. Then, the review also discusses the potential of biomass materials in BISSG applications, aiming to provide a theoretical basis for developing cost‐effective, efficient, and sustainable water purification technologies. Finally, the challenges and development prospects of the BISSG system in basic research and practical application will provide theoretical guidance for the further development of this technology.
