Summary
Solar-driven desalination has emerged as a promising sustainable approach to address global freshwater scarcity by converting saline water into potable water using abundant solar energy. Among various strategies, chalcogenide-based materials have attracted increasing attention due to their excellent light absorption properties, tunable band structures, and efficient photothermal conversion capabilities.
This Special Issue aims to highlight recent advances in chalcogenide materials for solar-driven water evaporation and desalination. The focus is on the design, synthesis, and interface engineering of sulfides, selenides, and tellurides, as well as their integration into high-performance photothermal systems.
Topics of interest include experimental, theoretical, and modeling studies on:
· Chalcogenide-based photothermal materials for solar evaporation
· Interface engineering for enhanced energy conversion efficiency
· Nanostructured sulfides/selenides for water purification
· Solar-driven membrane distillation enabled by chalcogenide materials
· Mechanistic understanding of light absorption and heat generation
· Scalable fabrication and practical desalination applications
· Environmental and economic evaluation of chalcogenide-based systems
This Special Issue aims to promote the development of high-efficiency, low-cost, and scalable solar desalination technologies based on advanced chalcogenide materials.
