Our research interest is to employ chemistry, materials science, nanotechnology and surface science to tackle the challenges in electrochemical energy storage and conversion. We strives to understand material structures and properties at solid/liquid interfaces under electrochemical conditions and to establish design principles for new and improved electrocatalysts and battery materials for the electrochemical conversion reactions of carbon dioxide, water, hydrogen, lithium, sulfur, nitrogen, and hydrocarbons.

Electrocatalytic Carbon Dioxide Conversion
