Solar steam generation has great potential in alleviating freshwater crises, particularly in regions with accessible seawater and abundant insolation. Inexpensive, efficient, and eco-friendly photothermal materials are desired to fabricate sunlight-driven evaporation devices. Here, we have designed an economical strategy to fabricate a high-performance wood-based solar steam generation device. In current study, 3D-hierarchical CuSnS has been loaded on wood substrates of variable sizes via an in-situ solvothermal method. Considering the water transportation capacity and thermal insulation property of wood, an enhanced light absorption was achieved by a uniform coating of CuSnS on the inside and outside of the 3D porous structure of the wood. Thanks for the synergistic effect of CuSnS and wood substrate, the obtained composite endorsed high-performance solar steam generation with a steam generation efficiency of 90% and an evaporation rate as high as 1.35 kg mh under one sun.
太阳能蒸汽发电在缓解淡水危机方面具有巨大潜力，特别是在有可利用海水和丰富日照的地区。人们希望使用廉价、高效、环保的光热材料来制造阳光驱动的蒸发装置。在这里，我们设计了一种经济的策略来制造高性能的基于木材的太阳能蒸汽发生装置。在目前的研究中，通过原位溶剂热法将 3D 分层的 CuSnS 负载在不同尺寸的木材基底上。考虑到木材的输水能力和隔热性能，通过在木材 3D 多孔结构的内外均匀包覆 CuSnS，实现了增强的光吸收。由于 CuSnS 和木材基底的协同效应，所得到的复合材料具有出色的太阳能蒸汽发生性能，在 1 个太阳光照下，蒸汽生成效率达到 90%，蒸发速率高达 1.35kg m h。
