Up to now, the manners for utilization of solar energy mainly focus on three aspects including photoelectric, [6][7][8] photochemical, [9][10][11] and photo thermal conversion. [12,13] Among them, the solar-thermal conversion based on direct transfer solar energy to heat is the most competitive technology for solar energy utilization and thus has become the subject of both academic research and industrial efforts. [14][15][16][17] Based on this, solar-driven steam generation shows many advantages in various fields such as seawater desalination, [18][19][20] sewage treatment, [21] and liquid-liquid separation [22,23] as well as sterilization and hygiene systems. [24] Most importantly, it can provide an ideal strategy to obtain a large amount of freshwater via seawater desalination. [25][26][27] The demand for freshwater is predicted to grow by more than 40% and two-thirds of the world's population will suffer from the lack of clean water by 2025. [28] Developing highly efficient seawater desalination is thus one of the most important technologies to address the great issue of increasingly global water resource scarcity. Traditionally, steam generation using solar energy is based on heating bulk liquid, which requires either special vacuum conditions or costly high optical concentrations. Many seawater desalination technologies such as reverse osmosis, [29] capacitive deionization, [30] and membrane distillation [31] have been reported. However, these technologies are based on the conventional route and generally rely on complicated optical concentrators for enhancing the water evaporation efficiency. In particular, during the seawater desalination process, the converted solar energy was partly used to heat bulk water or was lost to the external environment. [32,33] Therefore, it is inevitable that the efficiency of conventional solar desalination devices decreases dramatically with increasing bulk water quantity.In comparison, interfacial solar steam generation technology that localizes heating on a thin layer of water rather than the water bulk is a more competitive alternative to current solar steam generation technologies. To achieve high efficiency of solar steam generation, three main factors including efficient solar energy receiver, low heat loss, and sufficient fluid supply need to be taken into consideration. [26,34,35] Developing an efficient solar energy receiver is the most important as it directly determines the solar-thermal conversion efficiency. So far, various photothermal conversion materials with wide Developing cost-effective interfacial solar steam generation devices based on advanced structured materials for water desalination is highly desired. Herein, a high-efficiency solar steam generation based on a novel solar energy receiver of carbon black (CB)-based composite nanofiber networks with designed integrated 2D water path is reported. The receiver having a two-layer structure is prepared by a one-step electrospinning a suspension of CB particles in cellulose acetate (CA) onto a porous PET ...

Mixed ionic-electronic conducting (MIEC) membranes have gained growing interest recently for various promising environmental and energy applications, such as H 2 and O 2 production, CO 2 reduction, O 2 and H 2 separation, CO 2 separation, membrane reactors for production of chemicals, cathode development for solid oxide fuel cells, solar-driven evaporation and energy-saving regeneration as well as electrolyzer cells for powerto-X technologies. The purpose of this roadmap, written by international specialists in their fields, is to present a snapshot of the state-of-the-art, and provide opinions on the future challenges and opportunities in this complex multidisciplinary research field. As the fundamentals of using MIEC membranes for various applications become increasingly challenging tasks, particularly in view of the growing interdisciplinary nature of this field, a better understanding of the underlying physical and chemical processes is also crucial to enable the career advancement of the next generation of researchers.

The world population is severely affected by water scarcity, and it is an alarming issue that needs to be addressed urgently. Seawater desalination by solar‐driven evaporation is a promising technique to produce clean water. However, it is energy intensive and directs to a low water yield under natural sunlight. Therefore, the developments of new photothermal materials can reduce required energy for desired evaporation rates for efficient freshwater yield. Indeed, chitosan and polypyrrole‐based polymers are natural cationic copolymers, and their nanocomposites present well deal of interest for hydrogel structures due to their hydratable skeletons, and solar‐absorbing nature. Here, we report in situ polymerized Fe2O3@PPy/chitosan hydrogels as lightweight evaporation structures for solar‐powered evaporation under brine solutions (3.5 wt%). The polymeric network of Fe2O3@PPy/chitosan hydrogels builds in cross‐linked macroporous water channels, self‐floating, and a wide range of omnidirectional solar absorption (96%). The state‐of‐the‐art evaporation experiments demonstrate an efficient evaporation rate of water (1.80 kg m–2 h–1) and enhanced solar‐to‐vapor conversion efficiency (91%) as compared to other carbon‐based evaporation structures, excluding heat losses under 1 kW m–2 (one sun). Of note, the ultra‐black hydrogel surface stored enough thermal energy (39.6°C) under one sun solar irradiance due to the cationic polymeric network of Fe2O3@PPy/chitosan. A single‐step process for a freshwater supply that has been purified from various contaminants shows the potential of this device for real‐world applications.
