研究室紹介
Professor Ilhan Kwon's research lab specializes in sustainable energy and environmental technologies, focusing on the valorization of organic waste streams such as livestock manure and biomass into valuable products like syngas, biochar, and biodiesel. The lab develops advanced catalytic and thermochemical processes to enhance energy recovery and reduce environmental impacts, with particular emphasis on carbon capture and utilization, photocatalytic air purification, and the design of functional materials for environmental remediation. Key research directions include catalytic pyrolysis, CO₂ utilization in waste-to-energy conversion, and the engineering of carbon-based materials for adsorption and catalytic applications.

4Photocatalytic oxidation is a promising approach to detoxify indoor air pollutants such as volatile organic compounds (VOCs). Among various photocatalysts, graphitic carbon nitride (g-C3N4) is notable for its relatively narrow bandgap (2.70 eV), which enables activation using visible light. However, its applications are hindered by the rapid electron-hole recombination. To overcome this issue, this study proposes the fabrication of oxygen-functionalized g-C3N4 and evaluates its performance in th
The economic viability of biodiesel (BD) production is highly dependent on conversion techniques using inexpensiveoil feedstocks. In this study, BD was synthesised by the thermally induced (non-catalytic) transesterificationof oil extracted from camellia seed (42.23 wt% lipid content). The BD yield from the non-catalytictransesterification of camellia oil was higher than that from the alkali-catalysed process. The BD yield from thealkali-catalysed transesterification of camellia oil for 60 min w
가축분뇨의 대량 발생에 따른 환경적 부담을 완화하기 위해 가축분뇨의 열분해를 가축분뇨 처리 방법 중하나로 제시하였다. 탄소 활용 측면에서, 열분해는 분뇨로부터 유용한 탄소 기반 물질을 생산할 수 있다는 장점이있다. 본 연구는 우분 열분해 과정에서 이산화탄소 적용에 따른 합성가스 발생 특성을 연구하기 위해 수행되었다. 실험결과, 이산화탄소 조건에서 600 ℃이상에서 일산화탄소 가스 발생량이 증가하는 것으로 나타났는데, 이는이산화탄소와 우분 유래 휘발성물질의 균질반응에 기인한다. 우분 열분해 시 합성가스 증대를 위해, Co/SiO2를활용하여 촉매 열분해 실험을 추진하였다. 촉매를 이용한 우분 열분해 시 합성가스인 수소와 일산화탄소가 모든온도 영역에서 크게 증가하는 것으로 나타났으며, 이를 통해 이산화탄소가 가축분뇨 열분해를 통한 합성가스 생산에활용 가능함을 알 수 있었다.
To abate the environmental burdens arising from CO2 emissions, biochar offers a strategic means to sequester carbons dueto its recalcitrant nature. Also, biochar has a great potential for the use as carbon-based adsorbent because it is a porousmaterial. As such, developing the surface properties of biochar increases a chance to produce biochar with great adsorptionperformance. Given that biochar is a byproduct in biomass pyrolysis, characteristics of biochar are contingent on pyrolysisoperating
