摘要:
太阳能驱动界面蒸发是海水淡化和废水处理最有前途的技术之一。开发成本低廉、制备方法简单及光热转换效率高的太阳能光热材料是该技术实现规模应用的关键因素。以水为溶剂，聚乙烯醇（PVA）为基体，二硫化钼（MoS2）为光热材料，通过一锅法制备了聚乙烯醇负载二硫化钼（MoS2/PVA）海绵。通过扫描电子显微镜和能量色散X射线谱仪、傅里叶变换红外光谱仪、X射线衍射仪、接触角分析仪和水蒸发测试仪表征了海绵的结构与性能。实验结果证实了MoS2成功负载在PVA海绵基体中。研究了MoS2的用量对MoS2/PVA海绵的光吸收性能、光热性能以及太阳能驱动界面水蒸发性能的影响。结果表明：当MoS2的质量分数为7.5%时，制备的MoS2/PVA海绵在1 kW/m2太阳光强度下具有最高的水蒸发速率，蒸发速率可达1.37 kg/（m2·h），约为纯水蒸发速率0.31 kg/（m2·h）的4.42倍，并且MoS2/PVA海绵的水蒸发效率达到93.1%。
Abstract:
Solar-driven interfacial evaporation is one of the most promising technologies for seawater desalination and waste water treatment. Low cost，simple preparation，and high photothermal conversion efficiency of solar photothermal materials are crucial factors for the successful large-scale application of this technology. In this work，water was used as the solvent，polyvinyl alcohol （PVA） as the matrix，and molybdenum disulfide （MoS2） as the photothermal material to prepare polyvinyl alcohol sponge loaded with molybdenum disulfide （MoS2/PVA） through a one-pot method. The structure and properties of the sponges were characterized by using scanning electron microscope and energy dispersive X-ray spectrometer，Fourier transform infrared spectrometer，X-ray diffraction，contact angle analyzer and water evaporation tester. Experimental results confirmed the successful loading of MoS2 into the PVA sponge matrix. The influence of MoS2 content on the light absorption performance，photothermal performance，and solar-driven interfacial water evaporation performance of MoS2/PVA sponge were studied. Results show that at a MoS2 mass fraction of 7.5%，the prepared MoS2/PVA sponge exhibited the highest water evaporation rate under a 1 kW/m2 solar intensity，reaching an evaporation rate of 1.37 kg/（m2·h），approximately 4.42 times higher than the pure water evaporation rate of 0.31 kg/（m2·h）， and the pure water evaporation efficiency of the MoS2/PVA sponge reached 93.1%.
