The Choi group, EML (Electrocatalysis and Materials Laboratory), is interested in electrocatalysis and electrochemical materials for highly effective energy storage and conversion systems. Main objective of the research is a fundamental understanding of intrinsic relationships between physicochemical properties of electrocatalysts and their reaction performance. Through the developments and applications of highly advanced analytical techniques, the complex electrochemical reaction mechanisms and the factors determining the activity, selectivity, and stability of electrocatalysts are investigated. Highly active and stable electrocatalytic materials are newly designed based on these fundamental understandings, and the EML ultimately aims to apply the new materials in diverse fields of electrochemical energy systems. Our materials have been applied in the low-temperature fuel cells, the fuel production from electrochemical CO2 conversion, and the peroxide production from electrochemical oxygen reduction. The EML would try to continue the development of innovative electrochemical energy storage/conversion materials for overcoming the global energy crisis through an in-depth understanding of electrocatalysis and the many scientific collaborations.
