Solar-driven interfacial evaporation is an eco-friendly solution for tackling the impending water scarcity the world is facing in our century. In this work, a solar-driven interfacial evaporator was prepared from cigarette butts loaded with petroleum coke powder (Filter-PetCoke), a by-product of the oil refinery processes, for the improvement of the absorption of the incident solar light. A comparison between a flat 2D and a 3D evaporator with a surface composed of orderly patterned protrusions of 2.1 cm was carried out to assess the influence of the evaporator configuration on the evaporation performance. The 3D evaporator (3D Filter-PetCoke) achieved by far the best performance (evaporation rate: 1.97 ± 0.08 kg m h and solar conversion efficiency: 93.2 ± 5.4%) among the prepared samples (3D Filter-PetCoke, 3D Filter, 2D Filter-PetCoke, and 2D Filter). In addition, this configuration seems to be adaptable for real and more massive operation because of the geometry of the evaporator. The high efficiency was ascribed to the good heat generation of the petroleum coke and the excellent heat management of the 3D structure of the evaporator. Moreover, this evaporator was resistant to multiple repeated usages without significant efficiency loss and capable of producing drinking water from seawater and ()-contaminated water. The findings in this work indicate that this evaporator is pertinent to real situations to supply safe freshwater very efficiently from chemically/biologically contaminated water.
太阳能驱动的界面蒸发是应对本世纪全球面临的迫在眉睫的水资源短缺问题的一种环保解决方案。在这项工作中，利用炼油过程中的副产品——负载有石油焦粉的烟头（过滤-石油焦）制备了一种太阳能驱动的界面蒸发器，以提高对入射太阳光的吸收。对具有2.1厘米有序图案化凸起表面的平面二维蒸发器和三维蒸发器进行了比较，以评估蒸发器结构对蒸发性能的影响。在制备的样品（三维过滤-石油焦、三维过滤器、二维过滤-石油焦和二维过滤器）中，三维蒸发器（三维过滤-石油焦）的性能最佳（蒸发速率：1.97±0.08千克·平方米·小时，太阳能转换效率：93.2±5.4%）。此外，由于蒸发器的几何形状，这种结构似乎适用于实际的大规模运行。高效率归因于石油焦良好的发热性能以及蒸发器三维结构出色的热管理。此外，这种蒸发器耐多次重复使用，效率无明显损失，能够从海水和（）污染的水中生产饮用水。这项工作的研究结果表明，这种蒸发器适用于实际情况，能够非常有效地从化学/生物污染的水中供应安全的淡水。
