X-ray spectroscopy to understand functional materials: instrumentation, applications, data analysis
Edited by E. Borfecchia, K. A. Lomachenko and K. Kvashnina
Synchrotron-based X-ray spectroscopy currently represents an essential tool to disclose the structural and physico-chemical properties of advanced materials and to track their response relevant to the target functional applications. This virtual issue of Journal of Synchrotron Radiation contains invited contributions focusing on the key role of X-ray spectroscopy to understand functional materials, emphasizing recent advances in methods, applications, and data analysis.

This study presents iterative Bragg peak removal with automatic intensity correction (IBR-AIC) for X-ray absorption spectroscopy (XAS), a new method targeting Bragg peak interference in the analysis of crystalline materials. Merging experimental techniques with sophisticated post-processing, which includes an iterative algorithm for scaling absorption coefficients and eliminating Bragg peaks, this approach demonstrates significant promise in improving the quality of XAS data for these materials.

Normalization of XANES data to the spectral area is shown to be a viable normalization method with an error of a few percent as evaluated by comparison with calculated spectra and spectra normalized to the edge-jump.

Operando high-resolution X-ray absorption spectroscopy of BiVO4 photoanodes was performed in an electrochemical cell at both cation absorption edges. Small but significant variations of the spectra induced by electrochemical polarization were detected which were interpreted in terms of changes in the occupation of electronic states.
