Solar-driven water steam generation is a promising strategy for seawater desalination and wastewater purification. However, oil contaminants commonly exist in real water resources, which drives us to design and fabricate photothermal materials with high efficient water steam generation and outstanding anti-oil-fouling ability. Herein, we developed a metal-phenolic network-coated cellulose foam (Fe/TA@CF), which exhibits not only superb hydrophilicity and underwater lipophobicity, but also achieves high water evaporation rate of ∼1.3 kg m h even in oil-polluted seawater under one sun illumination. In addition, Fe/TA@CF is demonstrated to be both anti-oil-fouling and anti-salt-fouling, which benefits to long-term evaporation in practical utilizations. Metal ions and oil contaminants in the condensed water vapor are almost eliminated after purification. We believe that this low-cost, biodegradable Fe/TA@CF paves a way for rationally designing and fabricating high-performance evaporator for oil contaminated water purification.
太阳能驱动的水蒸汽发生是海水淡化和废水净化的一种很有前途的策略。然而，油类污染物通常存在于实际的水资源中，这促使我们设计和制造具有高效水蒸汽发生和出色抗油污染能力的光热材料。在此，我们开发了一种金属-酚醛网络涂层纤维素泡沫（Fe/TA@CF），它不仅具有极好的亲水性和水下疏油性，而且在单阳光照下甚至在污染的海水中也能实现高达 1.3 kg m h 的高水蒸发率。此外，Fe/TA@CF 表现出抗油污染和抗盐污染的能力，这有利于在实际应用中进行长期蒸发。凝结水蒸气中的金属离子和油类污染物在净化后几乎被完全去除。我们相信，这种低成本、可生物降解的 Fe/TA@CF 为合理设计和制造用于油污染水净化的高性能蒸发器铺平了道路。
