In situ WAXS Study of Structural Evolution in LiFePO4 Waste-Derived Phosphate/FeNi Alloy OER Catalysts (2026)
Abstract
Performing in situ wide-angle X-ray scattering (WAXS) at the Australian Synchrotron to investigate the real-time structural evolution of phosphate/FeNi alloy catalysts derived from LiFePO4 black mass during their electrochemical activation and operation for oxygen evolution reaction (OER). This catalyst system exhibits promising OER performance due to dynamic phase transformation, alloy formation, and phosphate restructuring. The proposed WAXS experiment will enable direct correlation between the structural dynamics and catalytic activity, providing key insights into structure¿function relationships. Our study aims to support the rational design of earth-abundant electrocatalysts for green hydrogen production and other energy conversion applications.
