摘要
界面太阳能蒸发脱盐是一种低成本、环保、高效的海水淡化技术.通过自组装方法合成了2D-2D交联结构的石墨烯-MXene光热脱盐膜,讨论了不同厚度光热膜的微观结构、形貌、浸润性、光吸收等特性,以及这些特性与光热蒸发脱盐性能的关系.结果表明,1 kW/m2 太阳光辐照下,最优石墨烯-MXene光热脱盐膜在 0.2 mol/L盐水中的最高蒸发速率可以达到1.68 kg/(m2·h),效率为85.38%.
Abstract
Interfacial solar evaporation desalination is a low-cost,environmentally friendly and efficient seawater desalination technique.In this paper,the graphene-MXene photothermal desalination membranes with a 2D-2D crosslinked structure were synthesized by self-assembly.The microstructure,morphology,wettability,light absorption characteristics,and their relationships with the photothermal evaporation desalination performance of membranes with different thicknesses were investigated.Results indicate that under 1 kW/m2 solar irradiation,the optimal graphene-MXene photothermal desalination membrane reaches a maximum evaporation rate of 1.68 kg/(m2·h)with an efficiency of 85.38%in 0.2 mol/L saline solution.
