The emerging solar desalination by interfacial evaporation shows great potential for alleviating the global freshwater crisis. However, salt deposition on the whole evaporation surface during steam generation leads to a deterioration in the evaporation rate and long‐term stability. Herein, it is demonstrated that a hydrogel‐based 3D structure can serve as an efficient and stable solar evaporator by salt localized crystallization for high‐salinity brine desalination. Under the function of micron‐grade brine transport management and edge‐preferential crystallization promoted by this novel design, this 3D hydrogel evaporator exhibits a superior salt‐resistant property without salt deposition on the photothermal surface even in 20 wt% brine for continuous 24‐h illumination. Moreover, by virtue of the synergistic effect of the promising 3D structure and excellent water transport of hydrogel, the proposed evaporator possesses an excellent evaporation performance achieving 2.07 kg m−2 h−1 on average in a high‐salinity brine (from 10 to 25 wt% NaCl) under 1 sun irradiation, among the best values reported in the literature. With stable and efficient evaporation performance out of high‐salinity brine, this design holds great potential for its applications in sustainable solar desalination.

“…One of them is NIR photothermal conversion, where NIR light energy can be efficiently transferred into in situ heat via a nonradiative relaxation process of multitudinous photothermal nanomaterials, such as graphene oxides, [ 104 ] carbon nanotubes, [ 105 ] gold nanoparticles/nanorods, [ 106 ] MOFs, [ 107 ] and MXene. [ 108 ] Another method is to upconvert lower energy NIR light into in situ UV/visible light through a two‐photon absorption process or upconversion nanoparticles (UCNPs). [ 109 ] In this section, we introduce recent advances of bioinspired adaptive materials for emerging NIR applications, including NIR‐triggered biological technologies, NIR light‐fueled soft robotics, and NIR light‐driven supramolecular systems.…”

Infrared (IR) adaptation phenomena are ubiquitous in nature and biological systems. Taking inspiration from natural creatures, researchers have devoted extensive efforts for developing advanced IR adaptive materials and exploring their applications in areas of smart camouflage, thermal energy management, biomedical science, and many other IR‐related technological fields. Herein, an up‐to‐date review is provided on the recent advancements of bioinspired IR adaptive materials and their promising applications. First an overview of IR adaptation in nature and advanced artificial IR technologies is presented. Recent endeavors are then introduced toward developing bioinspired adaptive materials for IR camouflage and IR radiative cooling. According to the Stefan‐Boltzmann law, IR camouflage can be realized by either emissivity engineering or thermal cloaks. IR radiative cooling can maximize the thermal radiation of an object through an IR atmospheric transparency window, and thus holds great potential for use in energy‐efficient green buildings and smart personal thermal management systems. Recent advances in bioinspired adaptive materials for emerging near‐IR (NIR) applications are also discussed, including NIR‐triggered biological technologies, NIR light‐fueled soft robotics, and NIR light‐driven supramolecular nanosystems. This review concludes with a perspective on the challenges and opportunities for the future development of bioinspired IR adaptive materials.

“…[ 26,27 ] The principle is attributed to the higher chemical activity of MA than that of MX bonds and lone‐pair electrons of outer metal atoms, leading to the selective etching of A layers without breaking the MX bonds. [ 28,29 ] Owing to the presence of transition metal outer layer, the functional groups are inevitably attached to the surface of MXenes to generate surface terminations during the synthesis process, resulting in the idiosyncratic properties. [ 30,31 ] Unlike other 2D nanomaterials, the structures and properties of MXenes are largely relied on the ratio of M or X element and generated surface termination.…”

Single atom catalysts (SACs) have shown their noticeable potential and gradually become a new favorite in catalytic field due to the particular selectivity, high catalytic performance, and strong durability. The most important factor in the synthesis of SACs is the selection of appropriate support and formation of metal–support interaction. Among a large number of nanomaterials, MXenes can be utilized as benign supports for fixing SACs because of their expansive specific surface area, regulable bandgap, superior electronic conductivity, and strong mechanical stability. The structure and property of MXenes can be manipulated by changing transition metal elements and surface termination. Here, the uniqueness and superiority of MXenes as superexcellent supports for confining SACs are analyzed from structure and property. The synthetic strategy of MXene‐supported SACs is also summarized, especially emphasizing the immobilization of isolated atom against aggregation by utilizing the formidable metal–support covalent coordination interaction. In addition, the applications of MXene‐supported SACs in electrocatalytic field are highlighted, including hydrogen evolution reaction, oxygen evolution reaction, overall water splitting, oxygen reduction reaction, and nitrogen reduction reaction. Finally, the challenges and prospects are pointed out for the further understanding and practical application of MXene‐supported SACs in electrocatalysis.
