Hwang's group explores sustainable chemical cycles by developing electrochemical reaction/catalyst materials/integrated devices based on the understanding of the solid-liquid interface (electrode-electrolyte interfaces). Our ultimate reasearch goal is contributing to address critical energy and environmental issues by realizing clean and sustainable chemical production. Three major research topics are (1) electrochemical synthesis for carbon utilization, (2) nanomaterial synthesis for an electrocatalyst application, and (3) in-situ/operando electrochemical characterization for understanding the reaction pathways and the catalyst surfaces which can give a feedback for scientific research advances.
