The rise of solar steam generation is an effective strategy to mitigate clean water shortages. However, achieving further improvements in conversion efficiency and stability remains a challenge. Here, 1T/2H-MoS2 nanosheets were uniformly assembled on activated carbon fiber cloth (A-CFC) through a facial hydrothermal method, and a three-dimensional (3D)-artificial transpiration device (ATD) was prepared using the plant transpiration process. The combination of activated carbon fiber cloth and 1T/2H phase MoS2 exhibits high light absorption (∼97.5%), excellent mechanical stability, large evaporation area, and easy escape of vapor. Additionally, the 3D hollow cone of the MoS2/carbon fiber cloth can effectively reduce radiative and convective energy loss and then achieve the enhancement of energy collection from the environment. An outstanding evaporation rate of 1.61 kg·m–2·h–1 with an optimum conversion efficiency of 97% under one sun is reached. Based on the facile fabrication, excellent stability, and high solar conversion efficiency, this nature-inspired design of 3D 1T/2H-MoS2/A-CFC is expected to facilitate large-scale applications for seawater purification and desalination.

基于1T/2H-MoS2/活性碳纤维布的太阳能蒸汽发电三维人工蒸腾结构

太阳能蒸汽发电的兴起是缓解清洁水短缺的有效策略。然而,进一步提高转换效率和稳定性仍然是一个挑战。在这里,通过面部水热法将1T/2H-MoS 2纳米片均匀组装在活性炭纤维布(A-CFC)上,并利用植物蒸腾工艺制备了三维(3D)-人工蒸腾装置(ATD)。 . 活性炭纤维布与1T/2H相MoS 2的结合表现出高吸光率(~97.5%)、优异的机械稳定性、大蒸发面积和易逸出蒸汽。此外,MoS 2的 3D 空心锥/碳纤维布可有效减少辐射和对流能量损失,进而实现从环境中收集能量的增强。在一个太阳下达到了 1.61 kg·m –2 ·h –1的出色蒸发率和 97% 的最佳转换效率。基于易于制造、出色的稳定性和高太阳能转换效率,这种受自然启发的 3D 1T/2H-MoS 2 /A-CFC 设计有望促进海水净化和淡化的大规模应用。
