Abstract
Freshwater scarcity, exacerbated by environmental pollution, poses a significant global challenge. This study addresses these challenges by developing a Prussian blue/carbonized wood (PB/CW) photothermal composite for solar desalination. The PB/CW composite exhibits enhanced solar absorption and photothermal conversion. The integration of Prussian blue (PB) on the honeycomb structure of wood facilitates efficient water transport and minimizes heat loss, underscoring the composite’s potential in practical solar desalination applications. Under natural sunlight, the PB/CW system achieves an evaporation rate of 4.39 kg m-2h−1, demonstrating its high efficiency in converting solar energy into water evaporation. This work offers a novel and effective approach to designing low-cost, high-efficiency solar evaporators, advancing the field of sustainable desalination technology.
淡水匮乏因环境污染而加剧，对全球构成了重大挑战。为了应对这些挑战，本研究开发了一种用于太阳能海水淡化的普鲁士蓝/碳化木（PB/CW）光热复合材料。普鲁士蓝/碳化木复合材料具有更强的太阳能吸收和光热转换能力。普鲁士蓝（PB）与木材的蜂窝结构相结合，促进了水的高效传输，并最大限度地减少了热量损失，从而凸显了这种复合材料在太阳能海水淡化实际应用中的潜力。在自然阳光下，PB/CW 系统的蒸发率达到了 4.39 kg m-2h-1，这表明它能高效地将太阳能转化为水蒸发。这项工作为设计低成本、高效率的太阳能蒸发器提供了一种新颖有效的方法，推动了可持续海水淡化技术领域的发展。
期刊介绍：
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
