摘要
利用太阳能进行海水淡化是当前解决人类缺乏饮用淡水的最有效的手段之一,具有绿色无污染、清洁和能源利用持续度高的特点。然而,传统的体积式太阳能海水淡化的方式存在设备投资高和能源利用效率低的问题,限制了其进一步发展。近年来,将光热转换材料置于水体表面的浮动式太阳能海水淡化的方式兴起,该方法使太阳能驱动的水蒸发只发生在水和空气的界面处,克服了传统体积式海水淡化对整个水体进行加热导致的能源转换效率不高的问题。基于此,新型浮动式太阳能光热蒸发材料的研究成为热点。重点介绍了浮动式太阳能光热转换材料的基本特征、制备方法,以及在太阳能海水淡化方面的应用性能。最后,对太阳能光热蒸发材料的发展方向进行了总结和展望。
Solar steam generation is one of the most effective means to solve the problem of lack of fresh water for drinking.It has the characteristics of green,pollution-free,clean and high energy utilization.However,the traditional volume solar steam generation has the problems of high equipment investment and low energy efficiency,which limits its further development.In recent years,the solar energy driven water evaporation only occurs at the interface between water and air by the floating solar steam generation in which the photothermal conversion material is placed on the surface of the seawater.The problem of low energy conversion efficiency caused by heating the whole water by traditional volume seawater desalination is overcame.Based on this,the research of new floating solar photothermal evaporation materials has gradually become a hot spot.The basic characteristics and preparation methods of floating solar photothermal conversion materials and their properties in solar steam generation were introduced.Finally,the development direction of solar steam materials was summarized and prospected.
