Research Area
  1. Fundamental understandings of electrocatalysis
  2. Developments of new electrocatalytic materials
  3. Fuel cells and electrolyzers
  4. Electrochemical synthesis of useful products
  5. Development of the new analytical techniques
The Choi group, eCatLab, is interested in electrocatalysis and electrochemical materials for highly effective energy storage and conversion systems. The main objective of the research is a fundamental understanding of intrinsic relationships among electrode, electrolyte, and reaction behaviors. Electric double layer (EDL) structure and its effects on electrocatalysis are also the main research interests of the eCatLab. 
The complex electrochemical reaction mechanisms and the factors determining the activity, selectivity, and stability of electrocatalysts are investigated through the developments and applications of highly advanced analytical techniques. Highly active and stable electrocatalytic interfaces are newly designed based on these fundamental understandings. The eCatLab ultimately aims to apply them to diverse fields of electrochemical energy systems, including fuel cells, CO2/NOx electrolyzers, and etc.
