【摘要】 以泡沫镍（NF）为基底，并将其作为镍源，结合钼酸铵（钼源）和硫脲（硫源），通过水热法在NF骨架上原位生长出MoS₂/Ni₃S₂@NF（MNS@NF）复合光热材料。通过X射线衍射仪、扫描电子显微镜（SEM）和X射线光电子能谱仪对复合材料的结构和形貌进行了表征，并对复合光热材料的光吸收性能和界面蒸发性能进行了研究。结果表明，在模拟太阳光照(光照强度为1 kW·m^-2)下，水热反应温度为200℃、反应时间为24 h的条件下合成的样品MNS@NF-200-24的光吸收率达到91.7%，其在去离子水中的界面蒸发速率达到2.846 kg·m^-2·h^-1，界面蒸发效率达到95.6%。此外，还测试了MNS@NF-200-24在模拟海水中的界面蒸发速率，蒸发1 h后速率达到2.360 kg·m^-2·h^-1，界面蒸发连续12 h后稳定在2.000 kg·m^-2·h^-1，宏观表面无结晶盐析出。蒸发冷凝得到的水达到世界卫生组织（WHO）与美国环境保护署（EPA）饮用水标准。更多还原

【Abstract】 Using nickel foam（NF） as both the substrate and nickel source, ammonium molybdate as the molybdenum source, and thiourea as the sulfur source, MoS₂/Ni₃S₂@NF（MNS@NF） composite photothermal materials were in situ grown on the NF skeleton via the hydrothermal method. The structure and morphology of the composite material were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM）, and X-ray photoelectron spectroscopy（XPS）, and its light-absorption and interfacial-evaporation performance were studied. The results indicated that under simulated solar illumination(light intensity of 1 kW·m^-2), the sample MNS@NF-200-24 synthesized at a hydrothermal reaction temperature of 200 ℃ and reaction time of 24 h achieved a light absorption rate of 91.7%, a deionized water interfacial evaporation rate of 2.846 kg·m^-2·h^-1, and an interfacial evaporation efficiency of 95.6%. Additionally, the interfacial evaporation performance in simulated seawater was tested. After 1 h of evaporation, the rate reached 2.360 kg·m^-2·h^-1, and after 12 h of continuous interfacial evaporation, it stabilized at 2.000 kg·m^-2·h^-1, with no crystalline salt precipitating on the macroscopic surface. The water obtained through evaporation and condensation met the drinking water standards set by the World Health Organization（WHO） and the Environmental Protection Agency（EPA）.更多还原
