| 研究実績の概要 |
The work involved conducting extensive experimental studies aimed at identifying the most promising combinations of elements for developing high entropy alloy (HEA) nanostructures. We focused on a set of elements, including Fe, Co, Ni, Mn, and Cr, which have similar atomic size and electronegativity. To catalyze hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and chlorine evolution reaction (CER), we developed a single-step pyrolysis technique to synthesize a high entropy alloy of Cr, Mn, Fe, Co, and Ni on a conductive carbon substrate.
