摘要:

淡水資源短缺是全球面臨的重大問題，利用太陽能界面蒸發技術進行海水淡化是近年來發展的一種綠色解決方案。蒸發速率是太陽能界面蒸發技術重要的衡量指標，由于自然界太陽光的強度是一定的，蒸發速率主要受限于水的蒸發潛熱。太陽能蒸發器是太陽能界面蒸發系統的核心元件，利用太陽能蒸發器材料的化學基團和物理結構降低水的蒸發潛熱成為提升太陽能界面蒸發速率的重要途徑。首先對太陽能界面蒸發技術和太陽能蒸發器進行簡要介紹，然后對可降低水潛熱的太陽能蒸發器的研究應用進行詳細總結，重點對太陽能蒸發器降低水的蒸發潛熱的機制進行分析歸納，最后對可降低水潛熱的太陽能蒸發器的發展進行展望，以期為可降低水潛熱的太陽能蒸發器的后續研發提供參考，進一步提升太陽能界面蒸發技術在海水淡化領域的競爭力。

Abstract:

The shortage of fresh water resources is a major problem facing the world. Seawater desalination using the technology of solar-driven interfacial evaporation is a green solution developed in recent years. Evaporation rate is an important index of solar-driven interfacial evaporation. Because the intensity of natural sunlight is constant, evaporation rate is mainly limited by the latent heat of water evaporation. Solar evaporator is the core component of solar interfacial evaporation system. Reducing the latent heat of water evaporation through the chemical groups and physical structure modulations of solar evaporator materials turns into an important way to improve the solar interfacial evaporation rate. In this review, the technology of solar-driven interfacial evaporation and the knowledge of solar evaporator were briefly introduced firstly. And then, solar evaporators which can reduce the latent heat of water evaporation were presented in detail. In addition, the mechanism of reducing the latent heat of water evaporation with solar evaporators was analyzed and summarized. The prospect and future challenges of solar evaporators with the ability of reducing latent heat were discussed finally, so as to provide reference for the follow�瞮p research and development of solar evaporators with the ability of reducing latent heat, and further enhance the competitiveness of solar-driven interfacial evaporation in the field of seawater desalination.
