- Element Specificity: XAS can selectively probe different elements in a complex mixture, making it ideal for studying multi-component systems. - Non-destructive: The technique is non-destructive, allowing samples to be analyzed without altering their structure. - In-situ Measurements: XAS can be performed under various conditions (e.g., temperature, pressure, and chemical environment), enabling real-time studies of processes like catalysis. - Complementary Information: XAS complements other techniques such as X-ray diffraction and electron microscopy, providing a more comprehensive understanding of nanomaterials.
