标题： Spectrum Selective Interfaces and Materials towards Non-photothermal Saltwater Evaporation: Demonstration with a White Ceramic Wick

摘要： 大多数太阳能脱盐努力都是光热的：它们使用能尽可能吸收阳光的“黑色”材料来蒸发水。 这种“盐水沸腾”方法受到水的高热容量的限制，即其储存和释放热量的能力。 在这里，我们研究了一种坚硬的白色氮化铝wick的光增强蒸发，并提出了一种通过深紫外相互作用选择性地针对盐水键而不是整体加热的途径。 通过实验和分析，隔离了氮化铝中光吸收和加热的影响，我们提供了光驱动、光谱选择性非光热盐水蒸发的实验证据。 利用白色陶瓷wick中的这些光-物质相互作用可能实现低成本、低能耗的脱盐，减少传统太阳能技术的热岛效应，并有助于在干旱也是问题的新冷却技术。 显示英文摘要

摘要： Most solar desalination efforts are photothermal: they evaporate water with ``black'' materials that absorb as much sunlight as possible. Such ``brine-boiling'' methods are limited by the high thermal mass of water, i.e., its capacity to store and release heat. Here, we study the light-enhanced evaporation by a hard, white, aluminum nitride wick, and propose a route to selectively target salt-water bonds instead of bulk heating via deep-UV interactions. Through experiments and analyses that isolate the effects of light absorption and heating in aluminum nitride, we provide experimental evidence of a light-driven, spectrum-selective path to non-photothermal saltwater evaporation. Leverage of these light-matter interactions in white ceramic wicks may achieve low-cost, low-energy desalination, reduce the heat island effects of traditional solar technologies, and contribute to new cooling technologies where drought is also a concern.
