X-ray Fluorescence Microscopy Study of LiFePO4 Waste-Derived Phosphate/FeNi Alloy Catalysts for Efficient Oxygen Evolution Reaction (2026)
Abstract
Employing X-ray Fluorescence Microscopy (XFM) at the Australian Synchrotron to spatially resolve the elemental distribution in phosphate/FeNi alloy electrocatalysts derived from LiFePO4-waste black mass. These materials exhibit superior activity for the oxygen evolution reaction (OER), with performance hypothesized to be linked to the nanoscale heterogeneity of Fe, Ni, and P species. XFM will enable high-resolution mapping of the metallic and phosphate domains, clarifying structural-function relationships. This project will provide critical insights into how synthetic routes influence active site formation, enabling rational design of high-performance OER catalysts from industrial battery waste.
