Abstract In recent times, solar-driven desalination has emerged as a sustainable solution for the impending water crisis. Herein, we report a novel solar-driven steam generator manufactured from porous carbon derived from sweet lime peels (a food waste) and polyvinyl alcohol sponge for efficient steam generation and its application in solar seawater desalination. The solar steam generator fabricated with a unidirectional pathway design satisfactorily absorbed incoming solar illumination, provided localized heat at the air-water interface and produced steam at a rate of 1.386 kg m−2 h−1, exhibiting an excellent photothermal efficiency of 90.88% under 1 sun (1000 W m−2) illumination. Furthermore, the steam generator proved capable of maintaining its performance in lower solar intensities (

生物质衍生的多孔碳，用于出色的低强度太阳能蒸汽产生和海水淡化

摘要 近年来，太阳能驱动的海水淡化已成为解决即将发生的水危机的可持续解决方案。在此，我们报告了一种新型太阳能驱动蒸汽发生器，该蒸汽发生器由来自甜石灰皮（一种食物垃圾）和聚乙烯醇海绵的多孔碳制成，用于高效蒸汽产生及其在太阳能海水淡化中的应用。采用单向路径设计制造的太阳能蒸汽发生器令人满意地吸收了入射的太阳光，在空气-水界面提供局部热量并以 1.386 kg m-2 h-1 的速率产生蒸汽，在低温下表现出 90.88% 的优异光热效率。 1 太阳 (1000 W m−2) 照明。此外，事实证明蒸汽发生器能够在较低的太阳能强度下保持其性能（
