물을 환원하여 수소를 생산할 수 있는 전기화학적 공정인 물 분해 반응은 화석연료를 대체하는 녹색에너지 기술로서

큰 주목을 받고 있다. 하지만, 이러한 기술의 효율과 장기 안정성 관점에서 산소 발생 반응(Oxygen evolution reaction,

OER)의 느린 반응 속도와 심각한 비활성화 문제로 인해 수소 생산을 위한 산업분야에서는 아직까지 제한되고 있어 이를

해결하기 위한 수많은 도전이 수행되고 있다. 본 연구에서는 알칼리 매질에서 산소 발생 반응에 필요한 과전압보다 낮은

과전압이 요구되는 Glucose 산화 반응(Glucose oxidation reaction, GOR)을 통해 부가가치가 높은 Glucose를 Glucaric

acid으로의 전환뿐 아니라 H2 발생 반응을 개선할 수 있는 Ce doped 된 NiFe 층상 이중 수산화물 촉매를 개발하였다.

The water electrolysis reaction, an electrochemical process that produces hydrogen through the reduction

of water, is gaining significant attention as a green energy technology to replace fossil fuels. However, the efficiency and

long-term stability of this technology remain limited in industrial hydrogen production due to the slow reaction rates and

serious deactivation issues associated with the oxygen evolution reaction (OER). Consequently, there are numerous

challenges to address. In this study, we developed a cerium-doped nickel-iron layered double hydroxide catalyst that

enhances hydrogen generation and facilitates the conversion of high-value-added glucose to glucaric acid via the glucose

oxidation reaction (GOR). This reaction requires an overpotential that is lower than that needed for the oxygen

generation reaction in an alkaline medium.
