“…Recent research on generating solar steam has focused primarily on exploring photothermal materials with high absorption in the solar spectrum. Many researchers have investigated plasmonic absorbers [29] and noble metallic and nonmetallic nanoparticles such as NiO nanoparticles, [30] MoS 2 nanosheets, [31][32][33][34] processed wood, [35][36][37] activated carbon, [38,39] carbon nanotube, [40][41][42] carbon black, [43][44][45] carbon foam, [43,[45][46][47] carbon fiber, [48][49][50] graphene and graphene oxide, [39,[51][52] Au nanoparticles [53][54][55][56][57] on finding efficient photothermal conversion materials for the top layer to absorb the incident solar irradiation and convert it into heat energy. Many research groups [58][59][60][61] demonstrated the use of 3D porous graphene/carbon hybrid aerogels as photothermal material and achieved significantly higher photothermal efficiency under 1 sun (1 sun = 1 kW m −2 ) illumination.…”

energy sector's two-superseding obstacles on the road to a sustainable future. [1][2][3] As the proven reserves of fossil fuels decrease, renewable energy sources have been sought in high demand, of which solar power is the most promising and potentially limitless source of energy in the foreseeable future. The energy from the sun to the earth is as high as 3 × 10 24 Jules per year, just 0.1% of the total solar resource would be sufficient to satisfy the annual worldwide energy demand. At present, solarsteam generation, which particularly refers to solar vapor under 100 °C, is considered to be one of the most promising sectors among other solar energy harvesting technologies owing to its potential applications in modern power plants, chemical plants, liquid-liquid phase separation, water purification and desalination, wastewater treatment, and many others. [4,[7][8][9][10][11][12][13][14] Among which water purification and desalination are gaining a lot of interest due to the recent lack of drinkable clean water supplies across the globe. Other competitive technologies for the production of freshwater, such as solid-liquid extraction, [13,15] electrochemical analysis [16,17] membrane-based separation, [18,19] etc. have many drawbacks, including high energy usage, possible environmental emissions, high infrastructure capital costs, etc.However, the efficiency of the traditional solar-steam generation method is below 24%, even with a high optical concentration ratio. [20] The traditional approach involves water evaporation by converting solar radiation directly to heat for steam generation commonly by using bulk metals. These bulk metals are inefficient in absorbing the solar spectrum and transferring heat through bulk water. As a consequence, its performance is limited by localized heat generation and transfer losses. [12,20,21] By contrast, interfacial solar vapor generation (ISVG) can localize the heat on the evaporation surface and, rather than the whole water, selectively heating the evaporation portion to minimize heat transfer to the water and significantly increase the solar evaporation efficiency. Therefore, ISVG has emerged as a novel concept for the solar steam generation with higher efficiency, attributes to the recent developments in nanoscale structural design with efficient photon and thermal management known as photothermal conversion materials. [1,[22][23][24][25][26] The photothermal conversion materials should have strong solar absorption and low thermal conductivity to achieve greater efficiency. [6,12] Moreover, it is also desirable to have superior hydrophilicity and porosity for fast water and A chemically treated luffa sponge (LS) derived from the ripe fruit of the Luffa cylindrica (LC) plant is investigated as an efficient solar photothermal conversion material for water purification applications for the very first time. Hydrophilicity and solar absorbance of the LS are enhanced by dopamine treatment and candle soot surface coating. The fabricated surface modified LS (SM-LS) leads to a sup...

“…However, a large amount of non‐renewable matter is used in the preparation of these materials. In order to reduce the dependence on non‐renewable energy in the process of solar‐driven steam generator, some research groups have begun to use low‐cost biomass materials as carbon source for solar steam generator, such as silk, 16 cotton, 17 mushrooms, 18 wood, 19 bamboo, 20 kelp, 21 lotus leaf, 22 and so on.…”

Summary Water transport capacity is one of the key factors for solar steam generation. Inspired by the transportation of water by vascular bundles in plants, the economical carbonized loofah (CL) with reticular structure and MOF‐801 with water absorption and rich pores were selected to form a solar evaporator. As vascular bundles, MOF‐801 provides abundant channels for rapid water transfer within the light absorbing layer. The excellent photothermal conversion performance of CL provides sufficient heat to convert the water quickly transported to the top of the light absorption layer into steam in time, just like plant transpiration. Thus, the evaporation efficiency of water was improved. The results show that MOF‐801@CL composite has excellent hydrophilicity. Under an optical density of the 1 kW m−2, the water evaporation rate of MOF‐801@CL was 1.42 kg m−2 h−1, which was about 1.2 times that of CL. The solar‐driven water evaporation efficiency reaches 88.9%. Furthermore, MOF‐801@CL has excellent stability in water evaporation and has great application potential in water purification. This design principle provides a potential way to improve the performance of solar steam generation and preparing solar water evaporation materials with high comprehensive benefit.

“…4 Three key factors play a signicant role for photothermal materials to improve the efficiency of SSG systems: (1) solar-thermal conversion capability, (2) water transportation rate, and (3) heat loss limitation. [2][3][4] Many different types of materials have been utilized to fabricate the photothermal materials for SSG systems, which can absorb higher than 90% of the sunlight, such as metallic nanoparticles, 5,6 semiconductors, 7,8 porous polymer, 9,10 and natural materials. 11,12 Additionally, the photothermal materials have hydrophilic properties, porous structure, and capillary system, which are able to transfer quickly enough water from the bulk to the surface for the evaporation process.…”
