Abstract:
High entropy alloys (HEAs), characterized by their unique equimolar multi-element composition and exceptional structural stability, have emerged as promising candidates for advanced electrocatalytic applications. In this research we will explore the design and development of HEAs as electrocatalysts for the oxygen evolution reaction (OER), a critical process in water splitting and renewable energy conversion technologies. By systematically designing the possible elemental combinations, we will identify compositions that maximize catalytic activity, stability, and resistance to corrosion under alkaline conditions. Advanced characterization methods, including transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDS) will help reveal active sites driving OER activity and the optimal metallic combination. Our goal is to design and characterize HEAs with high activity and stability in OER under alkaline conditions.
All interested students and faculty members are invited to attend.
