“…Interfacial solar steam generation (ISSG) has been considered as an effective technique to produce drinking water from various water resources, such as saline water and contaminated water. [1][2][3][4][5][6][7][8][9][10][11] As a green technology, ISSG not only absorb solar radiation and localize the heat impressively, [12,13] but also it does not require water pumping and equipment for water treatment. [14,15] Therefore, these advantages make it more suitable with respect to other desalination techniques for low infrastructure regions especially in parts of the world that have plenty of sunlight.…”

Interfacial solar steam generation (ISSG) is a sustainable and environmental-friendly technology for seawater desalination and wastewater purification using green and sustainable solar energy. Herein, a robust and efficient interfacial solar steam generation device or photoabsorber for ISSG of seawater and wastewater treatment was designed by coating wood with trace amount of Pd nanoparticles (NPs) and reduced graphene oxide (RGO). High evaporation flux of 5.25 kg m À 2 h À 1 was achieved by Pd20/RGO80/wood (a piece of wood was coated with 80 and 20 mg L À 1 of Pd NPs and RGO as a top and bottom layer, respectively) under 3 kW m À 2 . The value of electrical conductivity of seawater decreased from 6000.0 to 5.8 μS cm À 1 after desalination. The durability test showed the photoabsorber was stable for 30 cycles. The total cost to evaporation rate of the device was calculated as 0.29�0.003 USD/(cm 3 h À 1 ). The photoabsorber also showed excellent performance in wastewater treatment in removal of dyes of methylene blue and Reactive blue 5. Also, the concentration of heavy metals of Zn 2 + , Cd 2 + , Pb 2 + , Fe 2 + , Ni 2 + , and Cr 6 + reduced from 1000 ppm to near zero in the presence of photoabsorber.

“…The earth is surrounded by water, but only 0.36% is drinking water and accessible to the consumer directly (Aziznezhad et al 2021). Moreover, the fast rising global population, demand increase for consuming and industrial drinking water will lead to a drinking water de ciency and spending of all its resources (Shakib et al 2021; Sharma, Chauhan, and Vaish 2021).…”

In this paper, a stepped solar still made of galvanized iron, exposed to a solar simulator at a light intensity of 904 W/m2, was experimentally studied. Iron ore, granite, and sponge as photoabsorber were utilized on the surface of the stairs to increase the evaporation efficiency and drinking water production. In each mode, experimental tests were conducted at three mass flow rates, including 0.195, 0.134, and 0.1 kg/min. The results showed that increasing the mass flow rate of the inlet feed water results in reducing the drinking water production and the evaporation efficiency in all three modes. In addition, the iron ore is able to save solar radiation energy inside itself well, and consequently the evaporation rate increases. The maximum drinking water production archived by using iron ore at a mass flow rate of 0.1 kg/min with an amount 715 ml/min. However, the corresponding value for granite, sponge, and base state was recorded 630, 555, and 515 ml/min, respectively. Also economic analysis showed that the lowest mass flow rate of feed water leads to the lowest price of the product via using iron ore (0.07 $/lit) which is comparable to reported techniques in the literature.

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.
