近日,我校材料科学与工程学院(文物保护科学与技术学院)光热转换材料的功能化调控及应用创新团队在光热界面水蒸发领域取得重要进展,相关研究成果以“Water Skin Effect and Arched Double-Sided Evaporation forBoosting All-Weather High Salinity Desalination”为题,发表于Wiley杂志社旗下的国际顶级期刊Advanced Energy Materials(影响因子29.698),并被邀请作为当期Frontispiece(扉页论文)进行高亮推荐。王成兵教授、硕士研究生卫丹为论文通讯作者,参与该工作的还有硕士研究生许珂圆和石国良。陕西科技大学为论文唯一署名单位,该论文的发表提高了我校在光热界面蒸发材料领域的国际影响力。
该工作制备了一种用于界面水蒸发的光热材料,提出了利用限域水肤效应和双面蒸发协同促进全天候高盐度界面水蒸发的策略。设计的拱形蒸发器在一个太阳辐照下显示出3.21kgm-2h-1(3.5wt%NaCl)和2.87kgm-2h-1(20wt%NaCl)的超高蒸发速率。此外,该拱形蒸发器可通过光热效应和焦耳热效应的耦合大幅提高蒸发性能,在1 kw m-2太阳辐射和5 V外加电压条件下,该蒸发器的蒸发速率可达5.5kgm-2h-1。该工作构建的高效太阳能脱盐和水-电发电的一体化的拱形双面蒸发器,在海水淡化和废水处理方面显示出巨大的应用前景。
