이 교수의 연구실은 전기화학적 반응을 활용한 탄소중립 에너지 사이클 실현을 목표로 하며, 주로 이산화탄소 환원 반응(CO2RR)과 다금속 산화물 전기촉매의 설계 및 기전 해석에 초점을 맞추고 있습니다. 단일 원자 촉매(SAC)와 이중 원자 촉매(DAC)를 정밀하게 설계하여 높은 전류 밀도와 선택성을 확보하고 있으며, 특히 철 기반 질소 도핑 탄소 기반 촉매의 구조-활동 상관관계를 규명하고 있습니다. 또한 망간, cobalt, iron을 포함한 스파이널 구조 다금속 산화물 나노입자를 활용해 촉매의 다원소 상호작용 메커니즘을 규명하고 있습니다.

Electrochemical reduction of CO2 (CO2RR) provides an attractive pathway to achieve a carbon-neutral energy cycle. Single-atom catalysts (SAC) have shown unique potential in heterogeneous catalysis, but their structural simplicity prevents them from breaking linear scaling relationships. In this study, we develop a feasible strategy to precisely construct a series of electrocatalysts featuring well-defined single-atom and dual-site iron anchored on nitrogen-doped carbon matrix (Fe1–N–C and Fe2–N–
Multi-metal oxide (MMO) materials have significant potential to facilitate various demanding reactions by providing additional degrees of freedom in catalyst design. However, a fundamental understanding of the (electro)catalytic activity of MMOs is limited because of the intrinsic complexity of their multi-element nature. Additional complexities arise when MMO catalysts have crystalline structures with two different metal site occupancies, such as the spinel structure, which makes it more challe
