太阳能水蒸发是一种原始的技术，但由于纳米光热吸收器的使用，在过去的五年里，人们的兴趣又恢复了。尖端的纳米光热材料可以利用全光谱的太阳辐射，具有极高的光热转换效率。此外，光热设计通过热管理和光滑水流通道的层次结构并行发展。事实上，将所有理想的功能整合到一个光热层中仍然是遥感地区有效产出清洁水的基本挑战。最近报道了一些具有前所未有的水蒸发速率的纳米光热原型，用于清洁水的生产。尽管在科学和实际执行方面取得了最新进展，但仍然存在许多障碍和困难。这篇综述旨在激励纳米环境研究团体推动实时太阳能驱动的清洁水生产。简要描述了纳米光热材料及其各自的光热机制、表面等离子体共振、非辐射弛豫和晶格振动。讨论了整个太阳能驱动的蒸汽产生过程、液体到蒸汽的产生和蒸汽冷凝，以及对蒸发速率限制的理论理解。综述了水能同步发电的双功能水能关系。此外，还提出了该领域面临的决定性挑战。
Solar‐powered water evaporation is a primitive technology but interest has revived in the last five years due to the use of nanoenabled photothermal absorbers. The cutting‐edge nanoenabled photothermal materials can exploit a full spectrum of solar radiation with exceptionally high photothermal conversion efficiency. Additionally, photothermal design through heat management and the hierarchy of smooth water‐flow channels have evolved in parallel. Indeed, the integration of all desirable functions into one photothermal layer remains an essential challenge for an effective yield of clean water in remote‐sensing areas. Some nanoenabled photothermal prototypes equipped with unprecedented water evaporation rates have been reported recently for clean water production. Many barriers and difficulties remain, despite the latest scientific and practical implementation developments. This Review seeks to inspire nanoenvironmental research communities to drive onward toward real‐time solar‐driven clean water production. Nanoenabled photothermal materials and their respective photothermal mechanisms, surface plasmon resonance, non‐radiative relaxation, and lattice vibrations are briefly described. The entire solar‐driven steam generation process, liquid to vapor generation, and vapor condensation along with a theoretical understanding of evaporation rate limitations is discussed. The bifunctional water‐energy nexus is reviewed for simultaneous water and electricity generation. In addition, the decisive challenges of this field are put forward.
