What is X-ray Absorption Near Edge Structure (XANES)?
X-ray Absorption Near Edge Structure (XANES) is a powerful analytical technique used to investigate the local geometric and electronic structure of materials. In the context of catalysis, XANES provides crucial information about the oxidation state, coordination environment, and electronic structure of catalytic active sites. The technique involves measuring the absorption of X-rays as their energy is varied across the absorption edge of a specific element within a material.
