Abstract

Solar-driven water evaporation is a promising technology of freshwater production to address the water scarcity. However, the photothermal material and the distilled water would be contaminated in the evaporation of wastewater including organic pollutants. In this work, MOF-derived C/TiO₂ composites (carbonized UiO-66-NH₂ (Ti)) with simultaneous photothermal and photocatalytic functions are designed for producing freshwater from sewage. With advantageous features of porous structure with large specific area, excellent sunlight absorption and super-hydrophilicity, the carbonized UiO-66-NH₂ (Ti) layer exhibits high water evaporation efficiency of 94% under 1.0 sun irradiation. Meanwhile, the layer can simultaneously decompose the organic pollutants with degradation efficiency of 92.7% in the underlying water during solar-driven water evaporation. This bifunctional material will provide a new approach for solar-driven water evaporation and photocatalytic degradation of organic pollutant synergistically.

同时光热和光催化MOF衍生的C/TiO2复合材料用于高效太阳能驱动的污水净化

太阳能驱动的水蒸发是一种很有前途的淡水生产技术，可以解决水资源短缺问题。但在含有机污染物的废水蒸发过程中，光热材料和蒸馏水会受到污染。在这项工作中，mof衍生的C/TiO2复合材料(碳化UiO-66-NH2 (Ti))具有同时光热和光催化功能，用于从污水中生产淡水。碳化后的UiO-66-NH2 (Ti)层具有比表面积大、吸水性好、超亲水性好的多孔结构，在1.0太阳照射下蒸发率高达94%。同时，在太阳能驱动蒸发过程中，该层能同时分解下伏水中的有机污染物，降解效率为92.7%。这种双功能材料将为太阳能驱动水蒸发和光催化降解有机污染物提供新的途径。
