“…For example, the cellulose membrane with a microporous structure allows for rapid replenishment of surface water through capillary effect while reducing heat loss from the photothermal layer to bulk water by virtue of its low thermal conductivity. [ 60b ] Considering that the heat of water‐absorbing materials is easily dispersed into water and causes heat loss, [ 272 ] it is of great significance to choose a suitable water‐absorbing material with a lower thermal conductivity than water, thus effectively reducing the conduction heat loss. In order to achieve a balance between continuous water transport and insulation to reduce heat loss, the design of water transport also deserves attention, and different types of water transport structures have been developed, including 1D, 2D, and some 3D water transport paths ( Figure ).…”

“…This is because excessive water supply may result in frequent heat exchange and ineffective heating, and a large amount of water is heated but not converted into steam. [ 271c,272 ] Maintaining the appropriate water content in the photothermal layer can suppress unnecessary energy consumption. [ 235c ] Therefore, the water delivery rate should not be too fast, otherwise the resulting heat loss will be significant.…”

Global energy and environmental problems are becoming increasingly prominent, and the shortage of freshwater resources has been plaguing many countries and regions in the world. Solar steam generation (SSG) has emerged as a green, low‐cost and efficient strategy for freshwater production, which has attracted enormous attention in recent years. Furthermore, various photothermal materials and structural designs for the preparation of efficient SSG systems have been widely reported. Among them, metal‐based photothermal materials are abundant, and the exploration on metal‐based SSG systems is one of the important research directions. In this review, the basic concepts and design objectives of current metal‐based SSG systems are first introduced, as well as advances in the recent development of metal‐based photothermal materials, including photothermal mechanisms, and preparation methods. The evaluation criteria of the SSG system are further described. Then the development of metal‐based SSG systems is summarized in terms of structural design, functional modules (light absorption, thermal management, water transport, salt rejection, etc.), and potential applications (wastewater treatment, sterilization and other fields). Finally, the main challenges and future prospects of metal‐based SSG systems in basic research and practical applications are emphasized.

“…Among them, 3D solar steam generators are considered to be the most promising materials owing to their high water evaporation rates and versatility. [11][12][13] In general, 3D solar steam generators have large thicknesses, which is conductive to reduce thermal dissipation from evaporation surface to bulk water and also enhance the energy efficiency by allowing multiple reflections of light inside the 3D solar steam generators. Moreover, the 3D structure provides more feasibility for structural design.…”

Solar steam generation is a promising water purification technology due to its low‐cost and environmentally friendly applications in water purification and desalination. However, hydrophilic or hydrophobic materials alone are insufficient in achieving necessary characteristics for constructing high‐quality solar steam generators with good comprehensive properties. Herein, novel hydrophile/hydrophobe amphipathic Janus nanofibers aerogel is designed and used as a host material for preparing solar steam generators. The product consists of an internal cubic aerogel and an external layer of photothermal materials. The internal aerogel is composed of electrospun amphipathic Janus nanofibers. Owing to the unique composition and structure, the prepared solar steam generator integrates the features of high water evaporation rate (2.944 kg m−2 h−1 under 1 kW m−2 irradiation), self‐floating, salt‐resisting, and fast performance recovery after flipping. Moreover, the product also exhibits excellent properties on desalination and removal of organic pollutants. Compared with traditional hydrophilic aerogel host material, the amphipathic Janus nanofibers aerogel brings much higher water evaporation rate and salt resistance.

“…Solar‐powered evaporation presents an inventive and eco‐friendly approach for water purification, utilizing solar energy to facilitate the water evaporation process and separate it from contaminants [3,4] . Recently, studies focusing on the development of solar absorber systems, which incorporate photo‐thermal materials into a porous structure, have demonstrated the potential to significantly enhance the efficiency of solar‐to‐thermal conversion and elevate water evaporation capacities [5–7] . Nonetheless, there is a scarcity of studies addressing the significance of employing straightforward and expeditious fabrication methods for solar absorber materials, which not only circumvents extensive transportation but also offers facile degradability and retrieval, thereby minimizing storage constraints in real‐world applications.…”

Rapid population growth and water contamination have led to a shortage of freshwater, making it crucial to find sustainable methods for water purification. Solar‐powered evaporation is an eco‐friendly approach that uses solar energy to facilitate water evaporation and separate it from contaminants. Recent studies have focused on the development of solar absorber systems that incorporate photo‐thermal materials into a porous structure to enhance the efficiency of solar‐to‐thermal conversion and elevate water evaporation capacities. However, there is a lack of studies on simple and quick fabrication methods for solar absorber materials that minimize storage constraints in real‐world applications. Frontal polymerization (FP) technology is a promising solution that offers straightforward operation, minimal energy consumption, and rapid reaction for porous polymers. In this study, a decomposable and photo‐thermal composite polymer(LI/(P(DCPD‐co‐DTD))) is synthesized using FMORP, incorporating lignin fillers to improve the light absorption capacity and photothermal performance beneficial for water purification. The water evaporation rate can reach as high as 1.63 kg m−2 h−1. This composite polymer is expected to promote solar‐driven water purification in practical applications.
