Article Abstract
Molybdenum disulfide (MoS) has emerged as a promising photothermal material for solar desalination. However, its limitation in integrating with organic substances constrains its application because of the lack of functional groups on its surface. Here, this work presents a functionalization approach to introduce three different functional groups (-COOH -OH -NH) on the surface of MoS by combining them with S vacancies. Subsequently, the functionalized MoS was coated on the polyvinyl alcohol-modified polyurethane sponge to fabricate a MoS-based double-layer evaporator through an organic bonding reaction. Photothermal desalination experiments show that the functionalized material has higher photothermal efficiency. The evaporation rate of the hydroxyl functionalized the MoS evaporator evaporation rate is 1.35 kg m h, and the evaporation efficiency is 83% at one sun. This work provides a new strategy for efficient, green, and large-scale utilization of solar energy by MoS-based evaporators.

Global water scarcity demands next-generation desalination technologies that transcend the limitations of energy-intensive processes and salt accumulation. Herein, a groundbreaking interfacial solar steam generation system capable of simultaneous hypersaline desalination and ambient energy harvesting is introduced. Through hierarchical hydrogel architecture incorporating a central vertical channel and radial channels with gradient apertures, the design effectively decouples salt transport and water evaporation: solar-driven fluid convection directs water outward for evaporation, while inward salt migration prevents surface crystallization and redistributes excess heat.

Solar-driven desalination has emerged as a sustainable and efficient solution for addressing global water scarcity, especially beneficial in remote, off-grid, and disaster-affected regions. Among emerging technologies, photothermal membrane distillation (PMD) stands out due to its effective solar-energy conversion, scalability, and simplicity. Here, we report a hybrid PMD membrane fabricated by electrospinning MXene (TiCT) nanosheets integrated with silver nanoparticles (AgNPs) onto a poly(vinylidene fluoride--hexafluoropropylene) (PH) substrate.
