정길서 교수의 연구실은 전기화학적 에너지 변환 및 저장 기술에 초점을 맞추고 있으며, 특히 이산화탄소 환원, 수소 생산, 메탄올 산화 반응 등에서 높은 성능을 보이는 나노구조 전기촉매를 개발하고 있습니다. 다양한 전기화학적 방법(예: 전기진열, 고체합성, DES 유도 합성)을 활용해 촉매의 구조·형상 제어를 통해 반응성과 선택성을 극대화하는 데 주력하고 있습니다. 또한 초임계 상태의 CO₂ 저장 및 생물유래 화합물의 고가치 연료 전구체로의 전환 기술에 대해서도 연구를 확장하고 있습니다.

A room-temperature synthesized NiFeCe<sub>2</sub> electrocatalyst delivered a current density of 10 mA cm<sup>−2</sup> at a cell voltage of 1.59 V when used as the electrolyzer.
In this study, the deep eutectic solvent (DES)-aided synthesis of γ-CoV2O6 under modest reaction conditions using 1:1 choline chloride–malonic acid was reported. In the presence of DES, the reaction occurred at a lower temperature (500 °C) compared with that of the respective conventional solid-state synthesis of metal oxides and also with the calcination process involving the metal salts, thereby decreasing the overall formation energy. Differential scanning calorimetry revealed a 2-fold decrea
This paper presents experimental and simulation studies to evaluate the feasibility of sequestering supercritical CO2 in depleted gas reservoirs. Experimental results were simulated to obtain gas-liquid relative permeability curves used in the field simulation study. A 3D simulation model of one-eighth of a five-spot pattern was constructed to evaluate injection of supercritical CO2 under typical field conditions.
Abstract Herein, we report the controlled and direct fabrication of Cu 2 O/CuO thin film on the conductive nickel foam using electrodeposition route for the electrochemical reduction of carbon dioxide (CO 2 ) to methanol. The electrocatalytic reduction was performed in CO 2 saturated aqueous solution consisting of KHCO 3 , pyridine and HCl at room temperature. CO 2 reduction was carried out at a constant potential of −1.3 V for 120 min to study the electrochemical performance of the prepared ele
Co(OH)<sub>2</sub> nanoflakes directly grown on Ni foam using an electrodeposition route exhibit a promising performance for electrocatalytic oxidation of methanol.
