摘要
太阳能驱动的界面蒸发是从海水中生产淡水的一项前景广阔的技术,但蒸发器表面的盐分积累阻碍了其性能和可持续性。在本研究中,我们报告了一种制造三维多孔石墨烯螺旋辊(3GSR)的简单而绿色的策略,这种辊可实现高效的太阳能蒸发、盐分收集以及从零液体排放(ZLD)的近饱和盐水中生产水。3GSR 的设计有利于能量回收、盐水径向输送和盐的定向结晶,从而使 25 wt% 的盐水在 1 太阳光照射下连续 48 小时的超高蒸发率达到 9.05 kg m-2 h-1。值得注意的是,其外表面的定向盐结晶不仅扩大了蒸发面积,还实现了 2.92 kg m-2 h-1 的超高盐收集率,从而实现了 ZLD 海水淡化。此外,在室外测试中,3GSR 的产水率达到了创纪录的 3.14 kg m-2 h-1。这一创新解决方案提供了一种高效、连续的太阳能海水淡化方法,可用于制水和 ZLD 盐水处理,对解决全球水资源短缺和盐水处理引起的环境问题具有重大意义。
Highly efficient three-dimensional solar evaporator for zero liquid discharge desalination of high-salinity brine
Solar-driven interfacial evaporation is a promising technology for freshwater production from seawater, but salt accumulation on the evaporator surface hinders its performance and sustainability. In this study, we report a simple and green strategy to fabricate a three-dimensional porous graphene spiral roll (3GSR) that enables highly efficient solar evaporation, salt collection, and water production from near-saturated brine with zero liquid discharge (ZLD). The 3GSR design facilitates energy recovery, radial brine transport, and directional salt crystallization, thereby resulting in an ultrahigh evaporation rate of 9.05 kg m−2 h−1 in 25 wt% brine under 1-sun illumination for 48 h continuously. Remarkably, the directional salt crystallization on its outer surface not only enlarges the evaporation area but also achieves an ultrahigh salt collection rate of 2.92 kg m−2 h−1, thus enabling ZLD desalination. Additionally, 3GSR exhibits a record-high water production rate of 3.14 kg m−2 h−1 in an outdoor test. This innovative solution offers a highly efficient and continuous solar desalination method for water production and ZLD brine treatment, which has great implications for addressing global water scarcity and environmental issues arising from brine disposal.
