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.
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.
