Design and application of an electrochemical cell for operando X-ray diffraction and absorption studies for electrocatalysts.

ABSTRACT: The development of advanced catalysts for various electrochemical reactions necessitates precise characterization of their structure and dynamic evolution. This study introduces an innovative electrochemical cell tailored for operando X-ray characterizations, including X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS). The cell features an adjustable aqueous electrolyte window to reduce X-ray signal absorption and an integrated flow system for efficient removal of gas products. This design enables simultaneous XRD and XAFS measurements in both fluorescence and transmission modes. Using LiCoO₂ as a model oxygen evolution reaction catalyst, operando measurements reveal structural transformations during the reaction. This device will aid in the exploration of catal
