| 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 aim of this project is to develop robust and effective high-entropy alloy (HEA) based nanostructures and apply them in next-generation energy devices. During the period from April 2023 to March 2024, we have focused on summarizing a couple of projects on FeCoMnNiCr-based HEA carbon nanocomposites and other HEAs such as PtPdRuMoNi and PtPdRuIrRh. In addtion, we have investigated hydrogen/oxygen evolution and nitrogen/oxygen reductions to explore their potential applications.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
非常にチャレンジングなテーマをやっているので，論文成果発表が少々遅れているが，数カ月以内にはインパクトの高いジャーナルに採択させると期待している。
|
| Strategy for Future Research Activity |
The practical application of these HEA-based nanostructures will be evaluated in various electrochemical processes, such as hydrogen/oxygen evolution and oxygen reduction reactions, which are crucial for next-generation energy storage and conversion devices.
This involves identifying the best combination of metals, both precious and non-precious, to create a single-phase system with more than five elements and optimizing their geometrical and electronic structures.
