Cover Feature: Floating Photothermal Hydrogen Production (ChemSusChem 2/2025)

The Cover Feature shows a floating solar heating system with three key elements: a buoyant carrier with a hierarchical porous structure, a photothermal material that converts solar energy into thermal energy, and a photocatalyst that produces hydrogen. The floating photothermal system uses solar radiation to generate steam, and then with the help of the hierarchical porous structure, the steam quickly diffuses to the active sites to achieve sustainable hydrogen production.
