Desalinating seawater is a crucial method for addressing the shortage of freshwater resources. High-efficiency, low-cost, and environmentally friendly desalination technologies are key issues that urgently need to be addressed. This work used as a matrix material and prepared @Fe-GA through a complexation reaction to enhance the water evaporation rate and photothermal conversion efficiency of seawater desalination. The concentration of the impregnation solution was further refined, and the bonding mechanism along with the thermal stability of the composite photothermal material was investigated, including an assessment of their photothermal conversion efficiency. The research results indicate that the evaporation rate of water in a 3.5% NaCl solution for @Fe-GA under light intensity conditions of one sun reached 1.72 kg·m·h, which was an increase of 44.5% compared to untreated It achieved a photothermal conversion efficiency of 95.1%, an improvement of 53.6% over untreated , and maintained stability and high evaporation performance (95.4%) even after prolonged rinsing. This work realizes the functional utilization of seawater desalination with and offers a novel approach for the development and use of wood-derived photothermal material.
海水淡化是解决淡水资源短缺的关键方法。高效、低成本且环境友好的海水淡化技术是亟待解决的关键问题。这项工作以[具体物质]作为基体材料，通过络合反应制备了@Fe-GA，以提高海水淡化的水蒸发速率和光热转换效率。进一步优化了浸渍溶液的浓度，并研究了复合光热材料的结合机制及其热稳定性，包括对其光热转换效率的评估。研究结果表明，在一个太阳光照强度条件下，@Fe-GA在3.5% NaCl溶液中的水蒸发速率达到1.72 kg·m²·h，与未处理的[具体物质]相比提高了44.5%；其光热转换效率达到95.1%，比未处理的[具体物质]提高了53.6%，并且即使经过长时间冲洗仍保持稳定性和高蒸发性能（95.4%）。这项工作实现了利用[具体物质]进行海水淡化的功能化应用，并为木质光热材料的开发和利用提供了一种新方法。
