Abstract

This study investigates the photothermal water evaporation efficiency of Janus-structured sponges prepared from Cu nanoparticles-decorated graphitic carbon nitride/polydimethylsiloxane nanocomposites (CuCN/PDMS) and melamine foam (MF). Photothermal performance evaluation under 1 sun irradiation revealed significant temperature enhancement attributed to the incorporation of carbon nitride (CN) and copper nanoparticles (Cu NPs). Furthermore, the synergistic effect of enhanced light absorption and plasmonic localized heat generation led to remarkable improvements in water evaporation flux and efficiency, particularly evident in the CuCN/PDMS@MF evaporator, which exhibited an efficiency of 84.9%. These findings demonstrate the potential of the devised evaporators for practical applications. Additionally, real-world testing with seawater confirmed sustained functionality and resistance to salt accumulation, further emphasizing the importance of PDMS and MF as key components in the design of efficient Janus evaporators for addressing water scarcity challenges.

Graphical abstract

Janus-structured sponges made from Cu nanoparticles-decorated graphitic carbon nitride/PDMS nanocomposites and melamine foam (CuCN/PDMS@MF) exhibit enhanced light absorption and plasmonic heat generation, significantly improving water evaporation efficiency and offering promising solutions for practical desalination applications

用于光热水蒸发的 Janus 蒸发器，包括氮化碳/聚二甲基硅氧烷纳米复合材料上涂覆的纳米铜颗粒，用于三聚氰胺泡沫塑料

本研究探讨了由纳米铜粒子装饰的氮化石墨碳/聚二甲基硅氧烷纳米复合材料（CuCN/PDMS）和三聚氰胺泡沫（MF）制备的杰纳斯结构海绵的光热蒸发水效率。在太阳光照射下进行的光热性能评估显示，氮化碳（CN）和纳米铜粒子（Cu NPs）的加入显著提高了温度。此外，增强的光吸收和等离子体局部发热的协同效应显著提高了水蒸发通量和效率，这在 CuCN/PDMS@MF 蒸发器中尤为明显，其效率达到 84.9%。这些发现证明了所设计的蒸发器在实际应用中的潜力。此外，使用海水进行的实际测试证实了该蒸发器的持续功能性和抗盐积累能力，进一步强调了 PDMS 和 MF 作为设计高效简纳斯蒸发器的关键部件在应对水资源短缺挑战方面的重要性。图文摘要由铜纳米颗粒装饰的氮化石墨碳/PDMS 纳米复合材料和三聚氰胺泡沫（CuCN/PDMS@MF）制成的简纳斯结构海绵表现出更强的光吸收和等离子体发热能力，显著提高了水蒸发效率，为海水淡化的实际应用提供了前景广阔的解决方案。
