Outline of Research at the Start

次世代二次電池や燃料電池の電極材料として持続可能な非白金資源を用いつつ、その特性を高効率・高活性な白金と同等にすることが求められている。この目標を達成するためには、デバイスの機能を支配しているエネルギー変換・貯蔵反応の微視的機構をより深く理解することが必要である。本研究の目的は、特に重要なエネルギー変換反応である水素発生反応(HER)と酸素還元反応(ORR)の非白金触媒を用いた場合における微視的機構を理解し、それをより活性化するための原理を明らかにすることである。

Outline of Final Research Achievements

The basic science toward understanding microscopic electrode process of multielectron transfer energy conversion reactions was carried out. We unveiled several key aspects on the complicated multi-step reactions, such as oxygen reduction reaction or multielectron mutication transfer processes.

Academic Significance and Societal Importance of the Research Achievements

国際目標である持続可能な開発目標(SDGs)に代表される世界的な環境・エネルギー問題解決のため、資源的制約のない材料による電気化学的エネルギー変換反応の高効率化や特性向上が求められている。具体例を挙げれば、非白金電極触媒を用いて酸素と水素から水と電気を合成する装置である燃料電池や、逆に電気を用いて水から水素を生産する水電解装置の普及が必要である。そして、その実現には基礎科学に立脚した非貴金属電極による微視的電極過程に関わる基本原理のより深い理解が必要不可欠である。本研究による成果は、これら重要な課題解決に貢献する基礎的な科学的知見を社会に提供した。
