이 교수의 연구실은 생물유기물에서 유래하는 산소 함유 화합물을 고부가가치 연료 및 화학물질로 전환하기 위한 이종 촉매 반응 기반의 청정 에너지 기술을 핵심으로 연구하고 있습니다. 특히 수상상태 수소화 반응(APH)과 수소탈산소화(HDO) 반응을 중심으로 고성능 이중금속 촉매 및 원자층증착(AlD)을 활용한 촉매 안정화 기술을 개발하고 있습니다. 생분해성 원료를 효율적으로 활용할 수 있는 촉매 설계 원리를 규명하고, 실용화 가능한 반응 조건에서의 촉매의 내구성과 활성도를 동시에 향상시키는 데 초점을 맞추고 있습니다.

Hydrodeoxygenation (HDO) using heterogeneous catalysts has received considerable attention as a way of converting biomass-derived oxygenates into renewable fuels and chemicals.
Glucaric acid, a promising bio-based chemical for the production of adipic acid, is produced on a commercial Pt/C catalyst <italic>via</italic> aerobic oxidation of glucose in water.
The reaction rate on a per site basis for aqueous-phase hydrogenation (APH) of propanal, xylose, and furfural was measured over various alumina-supported bimetallic catalysts (Pd–Ni, Pd–Co, Pd–Fe, Ru–Ni, Ru–Co, Ru–Fe, Pt–Ni, Pt–Co, and Pt–Fe) using a high-throughput reactor (HTR). The results in this paper demonstrate that the activity of bimetallic catalysts for hydrogenation of a carbonyl group can be 110 times higher than monometallic catalysts. The addition of Fe to a Pd catalyst increased t
A thin atomic layer deposition (ALD) TiO2 coating successfully stabilizes cobalt particles supported on TiO2 for aqueous-phase hydrogenation (APH) reactions by preventing leaching and sintering of cobalt. The uncoated conventional cobalt catalysts leach under the same conditions. Using Al2O3 coating of Co/γ-Al2O3 causes the formation of an irreducible cobalt aluminate phase which has no catalytic activity. The ALD TiO2 decorated cobalt catalyst is active for APH of a range of feedstocks includin
