“…The high evaporation rate of RGO-CF can be attributed to its large temperaturer ise, suggesting its excellent ability to convert light into thermal energy for efficient solar steam generation. The energy conversion efficiency h was calculated accordingt ot he literature [40][41][42] ;t he calculation is presented in the Supporting Information. As seen in Figure 7e,t he calculated h value of CF is 28.43 %u nder 1s un which is much lower than that of GO-CF and RGO-CF under the same solar intensity.R GO-CF possessed the highest energy conversion efficiency of 94 %u nder 1sun.…”

Solar steam generation by photothermal materials has recently emerged as a new and feasible approach to effectively harvest solar energy in a variety of applications. This work reports an efficient heat localization material based on the renewable cellulose acetate cigarette filters and a reduced graphene oxide coating (RGO‐CF) as the light‐to‐heat conversion layer for solar steam generation. RGO‐CF possessed an aligned structure with superhydrophilic nature, lower thermal conductivity (0.0733 Wm−1 K−1), and broad light adsorption (≈100 %). These characteristics enable rapid water transportation and excellent light‐to‐heat conversion by the resulting RGO‐CF with an energy conversion efficiency of 94 % under stimulated solar illumination (1 kW m−2), which demonstrates that RGO‐CF is a promising photothermal conversion material for solar steam generation. Such strategy for preparation of photothermal materials not only reduces the fabrication cost but also provides a fundamental guidance for the practical application of renewable polymer resources from used cigarette filters.

The lack of fresh water resources is attracting concern worldwide. Recently, to address this global issue, researchers proposed the heat localization concept for interfacial solar seawater desalination in 2014. Since then, interfacial solar steam generation (ISSG) devices have attracted much attention, due to their potential for achieving highly enhanced optical‐thermal conversion through a single interface as compared with traditional solar seawater desalination. To date, the promising prospect of ISSG systems in seawater desalination has stimulated the rapid development of solar desalination technology based on heat localization. To comprehensively recognize ISSG devices and acquire more insights into their design associated with biological relevance, efficiency improvement, and applications, this review summarizes the progresses and prospects of ISSG devices in relation to the evolution of advanced materials, the engineering architecture, the collaborative application, and the current challenges.

Summary A solar vapor generation system with a high evaporation efficiency and also a high mechanical strength is still attractive, while most previous works only focused on efficiency. Herein, we firstly prepared a carbon‐black/wood‐flour system with strength enhanced by polystyrene. Then, we investigated the effects of porosity, polystyrene content, and thermal insulation on the evaporation performance of the system. Experimental results indicate that the porosity of system can significantly affect the evaporation efficiency. With the increase of porosity, there exists an optimal porosity to obtain a high evaporation efficiency. A higher content of polystyrene, which could cause a lower thermal conductivity of the system, always gives a higher evaporation efficiency when the porosity is fixed. For polystyrene content of 60 wt% and system porosity of 36%, under a 1‐sun irradiation, there is an optimal evaporation efficiency of about 80.4%. Additionally, the fracture stresses of the system in dry and wet states could be as high as 2.18 and 2.03 MPa, respectively, which ensures the system strength. Considering the high efficiency, high mechanical strength, low cost, and easy preparation, this system has a good potential to be used in practical applications.
