Abstract

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 글루코스 산화 반응 (Glucose oxidation reaction, GOR)을 통해 부가가치가 높은 글루코스를 글루카릭산으로의 전환뿐 아니라 H2 발생 반응을 개선할 수 있는 Ce 도핑된 NiFe 층상 이중수산화물 촉매를 개발하였다.

Water electrolysis reaction, an electrochemical process that can produce hydrogen by water reduction, is receiving great attention as a green energy technology to replace fossil fuels. However, in terms of the efficiency and long-term stability of this technology, it is still limited in the industrial field for hydrogen production due to the slow reaction rate and serious deactivation problems of the oxygen evolution reaction (OER), so there are numerous challenges to solve. It is being carried out. In this study, a Ce doped NiFe layer double hydroxide catalyst that can improve the H2 generation reaction as well as the conversion of high-value-added Glucose to Glucaric acid was developed through the Glucose oxidation reaction (GOR), which requires an overpotential lower than the overpotential required for the oxygen generation reaction in an alkaline medium.
