Although the experiments referred to here demonstrate the wealth of kinetics and structural data that can be obtained from TR-XAFS data, application of XAFS spectroscopy combined with complementary techniques provides unique and even more detailed information. This statement refers to the most elegant way of using XAFS spectroscopy simultaneously with other methods (e.g., XRD Clausen, 1998 Clausen et al., 1993 Dent et al., 1995 Thomas et al., 1995), and it also refers to XAFS experiments complemented by experiments carried out under similar experimental conditions (e.g., laboratory techniques such as XRD, Raman spectroscopy, TG/DTA). More often than not, a detailed XAFS analysis is possible only when all additional data (characterizing phases, metal valences, and structure) representing the catalyst are available. Furthermore, the analysis of TR-XAFS data should aim at extracting as much information from the XANES part and the EXAFS part of a XAFS spectrum as possible.
