Solar-driven water evaporation has been considered as a promising strategy to solve the growing water shortage and water pollution problems. Developing low-cost and large-scale photo-thermal materials combined with highly efficient solar steam generation, water transport and environmental stability still remains a huge challenge. Herein, we proposed a design of Cu2S/Cu2O/Cu foam (Cu2S/Cu2O/CF) hierarchical structure through the interface engineering approach. The heterostructure contains the unique Cu2O/Cu2S core–shell nanowire and Cu foam substrate. The as-prepared Cu2S/Cu2O/Cu nanostructure achieved a high light absorption performance (96%), a high evaporation rate of 1.44 kg m−2 h−1 and a solar thermal conversion efficiency of 83.1% under 1 sun irradiation. The antifouling ability makes Cu2S/Cu2O/CF flexible in various kinds of water including polluted water and seawater. In addition, its excellent hydrophilic properties provide Cu2S/Cu2O/CF with anti-oil pollution capability, improving efficient water transport to the evaporator surface and purifying the raw water. The Cu2S/Cu2O/CF nanocomposite provides a promising route for freshwater production via solar distillation.

Cu2O / Cu2S核/壳纳米线的异质结构设计,用于太阳能驱动的光热水汽化脱盐
太阳能驱动的水蒸发被认为是解决日益严重的水短缺和水污染问题的有前途的战略。开发低成本,大规模的光热材料并结合高效的太阳能蒸汽产生,水输送和环境稳定性仍然是巨大的挑战。在此,我们通过界面工程方法提出了一种Cu 2 S / Cu 2 O / Cu泡沫(Cu 2 S / Cu 2 O / CF)分层结构的设计。异质结构包含独特的Cu 2 O / Cu 2 S核壳纳米线和Cu泡沫基质。制备的Cu 2 S / Cu 2在1次太阳照射下,O / Cu纳米结构获得了高的光吸收性能(96%),1.44kgm -2 h -1的高蒸发速率和83.1%的太阳热转换效率。防污能力使Cu 2 S / Cu 2 O / CF在包括污染水和海水在内的各种水中均具有柔性。此外,其出色的亲水性使Cu 2 S / Cu 2 O / CF具有抗油污能力,改善了水向蒸发器表面的有效输送,并净化了原水。Cu 2 S / Cu 2 O / CF纳米复合材料为通过太阳蒸馏生产淡水提供了有希望的途径。
