“…[14] On the other hand, our used black PUF and CNTs components in MSAE are well-known photo absorber with ultrastrong broadband absorbance and the absorbed photo-energy is mainly transformed into the heat. [15] Intimate attachment of CBPCNT onto the backbone of 3D macroporous PUF could synergistically render sufficient light-matter interaction, reduce the light reflection and improve the light collection.

“…Furthermore, the essence of distillation lies in the heating of a series of liquids with different boiling point to obtain desired substance. A good example in this respect is that Tsang's group adopted self‐floating black polyurethane (BPU) sponges to successfully separate an alcohol‐water mixture . As shown in Figure b, the dotted line represents the same concentration of ethanol in both the gas phase and liquid phase; and distillation with the BPU sponge can increase the purity of ethanol by up to 25% when its mass fraction is below 60%.…”

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.

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.
