“…Owing to remarkably suppressed heat loss to bulk water with the assistance of thermal insulation materials between the bulk water and photo‐thermal materials, the evaporation rate can be largely improved as compared to the traditional bulk water heating system. [ 13,14 ] For the solar‐driven water evaporation, photo‐thermal materials became one of the most important factors for solar energy using efficiency, which can harvest the solar light and deliver the energy to interfacial water for steam generation. [ 15 ] Nowadays, various sunlight absorbent materials have been developed for photothermal water vaporization.…”

Utilization of carbon materials for harvesting solar energy is a green, feasible, sustainable, and promising way to manufacture freshwater from sewage and seawater. However, sunlight absorption efficiency, light to thermal conversion efficiency, and expensive cost are still limitations for large‐scale solar steam generation. Here, a solar steam evaporator which is fabricated by carbonized willow catkins films and activated by different metal chlorides under nitrogen at 800 °C is demonstrated. Under the light irradiation intensity of one sun (1000 W m−2), water evaporation rate of the prepared evaporator is up to ≈2.17 kg m−2 h−1, and the surface temperatures reach up to 50 and 91.7 °C under water‐saturated and dry situations, respectively, indicating good steam generation ability and heat localization performance of the fabricated evaporator. The SEM, BET, DSC, and ICP‐MS results show that such a high water evaporation rate of the prepared carbon materials is due to the typical tubular micro‐structure, which decreases water enthalpy of evaporation and the water evaporation in the form of molecular clusters. This method of carbonized and activated willow catkins films provides a sustainable way for efficiently harvesting solar energy to produce fresh water from seawater and sewage.

“…Thus, the interfacial solar-driven evaporation has been considered as an Zhou et al designed a biosafety cuttlefish juice-based solar absorber to optimize the water-transport regulation, and the tailored absorber can block excessive useless water, and effectively reduce heat losses.

Realizing ultrathin water and generating an abundant water/air interface in the interconnected pores of photothermal materials is an effective way to boost the solar-driven water evaporation rate, but still a great challenge. Herein, confinement capillarity (CC) of photothermal thin coating on porous sponge for significantly enhancing the solar-driven water evaporation is proposed. The thin coating is composed of abundant agminated black/hydrophilic nanoparticles (BHNPs), and the channels among the BHNPs can generate strong capillarity for water transportation. Water can be spontaneously limited and transported among the agminated nanoparticles, rather than fill in the interconnected pores of the sponge. Thus, ultrathin water layer can be realized on the outer/inner surface of the sponge skeleton, without precisely controlling water supply. The thin water layer can not only expose as much evaporation area as possible by increasing the vapor escape channel, but also prevent solar energy to heat excess water. Thanks to the CC, the rate of solar steam generation can be greatly improved. Moreover, the photothermal material with CC can maintain its high evaporation rate during the whole day, and can remove the salt during night time, highlighting its recyclability and anti-salt-accumulation property. Moreover, the CC can be readily scaled up for practical applications.

“…And organic photothermal materials, e.g., organic polymer materials [ 16–18 ] and natural materials. [ 19–21 ] Although great progress has been made to this end, the reported photothermal materials have high evaporation rate, or have good salt resistance. However, still many challenges remain.…”

Solar steam generation (SSG) offers a clean and sustainable way to produce freshwater from seawater or polluted water by harvesting solar energy. However, it remains a great challenge to integrate all the desired functions in a single evaporation system by using low‐cost materials and simple methods. Herein, we report the design and fabrication of a novel inorganic solar steam evaporator (PPy‐HGMAM) through binding the building block of hollow glass microspheres (HGM) and pore‐forming material of melamine sponge (MS) with interconnection network structure by aluminum dihydrogen phosphate adhesive followed by coating of polypyrrole (PPy) as light absorption layer for efficient SSG. With the merits of high porosity, low thermal conductivity both in the wet (0.107 W m−1 k−1) and dry (0.056 W m−1 k−1) states, super‐hydrophilicity, and strong light absorption (92%), the as‐prepared porous PPy‐HGMAM shows high energy conversion efficiency (92.9%) and evaporation rate (1.56 kg m−2 h−1) under 1 sun (1 kW m−2) illumination, as well as excellent salt‐resistance performance. Combined with its high mechanical strength, self‐floating ability, environment‐friendly, and low cost, along with simple and scalable preparation method, our inorganic PPy‐HGMAM evaporator may hold the great potential for practical large‐scale application in SSG.
