“…Simultaneously, water purification could be realized by the effective removal of various ions (Na + , Mg 2 + , Ca 2 + and B 3 + ) and organic pollutants (such as Rhodamine B) during the evaporation process driven by the photothermal conversion mechanism, as shown in Figure 11(b) and (c). [150] Moreover, MXenes have been applied as the active ingredients in the absorbents for crude oil spills in marine environment. The fluidity of crude oil, associated with the absorbing capability of the absorbents, is determined by the viscosity which is temperature-dependent and decreases from above 10 Pa•s (at RT) to 0.02 Pa•s (at 60 °C).…”

The properties and applications of MXenes (a family of layered transition metal carbides, nitrides, and carbonitrides) have aroused enormous research interests for a decade since the successful synthesis of few‐layer transition metal carbides in 2011. Though MXenes, as the building blocks, have already been applied in various fields (such as wearable electronics) owing to the distinctive optical, mechanical and electrical properties, their thermal stability and intrinsic thermal properties were less thoroughly investigated compared to other characteristics in early reports. The pioneering theoretical prediction of the thermoelectric nature of MXenes was performed in 2013 while the first experiment‐based report concerning the degradation behavior of the 2D structure at elevated temperatures in a controlled atmosphere was published in 2015, followed by numerous discoveries regarding the thermal properties of MXenes. Herein, after a brief description of the synthesis, this Review summarized the latest insights into the thermal stability and thermophysical properties of MXenes, and further associated these unique properties with relevant applications by multiple examples. Finally, current hurdles and challenges in this field were provided along with some advices on potential research directions in the future.

Converting renewable solar energy into manageable thermal energy is significant for diverse applications. Nevertheless, integrating multifunctional solarto-heat coating on various substrates and achieving large-scale manufacture remains a challenge. Herein, Cl − doped poly(3,4-ethylenedioxythiophene) (Cl-PEDOT) coating on multiple substrates is successfully created using oxidative chemical vapor deposition (oCVD) without to be restricted to the changeable substrate surface chemistry (e.g., wettability), sizes as well as dimensions (2D-3D). Partial Cl − doping and spontaneously formed microstructures can remarkably enhance near-infrared absorption and hydrophilicity of coating. The Cl-PEDOT coating manifests many advantages: universality, scalability, low-cost, high efficiency, and stability. When used for solar steam generation, all Cl-PEDOT coated substrates represent reinforced evaporation performance. The universality makes it possible to optimize the evaporator performance by structural design. Structural design as optimized energy flow enables the pyramid array wood-based evaporator to set an evaporation record (≈1.19 kg m −2 h −1 , ≈91%) under the weak-light (0.5 sun). Moreover, a greenhouse and a crude-oil cleaner are designed to achieve eco-friendly, energy-saving solar-driven heating/dehumidification, and crudeoil recovery without additional energy input. This study reveals that welldesigned oCVD is a simple and straightforward way to engineer lightweight and thermally insulating polymers into multifunctional solar-to-thermal composites toward diverse solar-driven applications.

Solar steam generation is an efficient way to address global freshwater shortages. However, water evaporation suffers from either inefficient heat conduction or relies on expensive materials and complex equipment. Herein, a porous hydrogel (AC-H) with molecular meshes, micron channels, and internal gaps is fabricated and used for metal ion adsorption. AC-H exhibits excellent uptake ability and can attain the levels required by industrial water safety standards. Subsequently, the exhausted AC-H hydrogel is vulcanized in situ (AC-MS) and upcycled for solar steam generation resulting in ≈1.41 kg m −2 h −1 evaporation rate under one sun irradition, which reduces costs and converts the waste into a resource. Furthermore, a heat management strategy is developed where a cold surface of specific area is introduced between the AC-MSx and bulk water to adsorb the heat loss. When the cold area is increased, the energy in the bulk water can be extracted by the coldsurface. which enhances the water evaporation rate. Significantly, the theoretical simulations are in good agreement with the experimental results. Therefore, this research provides a novel strategy to upcycle exhausted materials for photothermal technologies and reduces the heat conduction during solar-to-thermal evaporation.
