Solar vapor generation through evaporation using photothermal materials is a promising candidate for seawater desalination. The TiC MXene membrane has exhibited photothermal behavior in solar water evaporation. However, dense packed two-dimensional (2D) MXene membrane with high reflection loss and insufficient vapor escape channels limited its solar evaporation performance. In this work, one-dimensional (1D) multi-walled carbon nanotubes (MWCNT) were added into 2D TiC nanosheets as the holder to form a 2D/1D hybrid photothermal membrane. Owing to the 2D/1D hybrid structure, more effective broadband solar absorption, water transportation and vapor escape were achieved.
利用光热材料通过蒸发实现太阳能蒸汽产生是海水淡化的一个有前景的候选方案。TiC MXene膜在太阳能水蒸发中表现出光热行为。然而，具有高反射损失和蒸汽逸出通道不足的紧密堆积二维（2D）MXene膜限制了其太阳能蒸发性能。在这项工作中，一维（1D）多壁碳纳米管（MWCNT）被添加到二维TiC纳米片中作为支撑体，以形成二维/一维混合光热膜。由于二维/一维混合结构，可以实现更有效的宽带太阳能吸收、水传输和蒸汽逸出。
