Outline of Research at the Start |
During this period, our goal is to write a manuscript on FeCoMnNiCr-based HEA carbon nanocomposites and publish it in a reputed journal. Additionally, we plan to investigate other material combinations such as PtPdRuMoNi and/or PtPdRuIrRh to develop promising mesoporous HEA nanostructures for sustainable hydrogen/oxygen evolution and nitrogen/oxygen reductions.

Outline of Annual Research Achievements |
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.

Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
Our method leveraged the synergistic effects of mixed metal (cocktail effect) high entropy alloys for enhanced catalytic performance.

Strategy for Future Research Activity |
We aim to write and publish a manuscript on FeCoMnNiCr based HEA carbon nanocomposites in a reputed journal. I also plan to explore PtPdRuMoNi and/or PtPdRuIrRh to develop mesoporous HEA nanostructures for sustainable reactions like hydrogen/oxygen evolution and nitrogen/oxygen reductions.
