X-ray photoelectron spectroscopy reveals the surface chemistry of bio-based hybrid materials

Just a few atomic layers at the surface can strongly influence how effectively a material binds pollutants from water or how efficiently a photocatalyst responds to light. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP use X-ray photoelectron spectroscopy (XPS) to investigate the chemical states and interactions at the surfaces and interfaces of bio-based carbon materials and organic-inorganic hybrid materials. Their insights can support the targeted development of functional materials for future industrial applications.
