The electrochemical interface is where the electron transfer between electrode/electrocatalyst/electrolyte happens. Understanding the interface reveals the structure-property relationship of electrocatalysts. In situ techniques are useful to study the interface. Our lab focuses on the following techniques: in situ UV-Vis and Raman spectroscopy, Atomic Force Microscopy, and X-ray diffraction.
In situ atomic force microscopy coupled electrochemistry (EC-AFM) for morphologic and structural detection during electrocatalysis
In situ mass spectroscopy for product detection during electrocatalysis
Electrocatalysts are materials that can promote electrochemical conversion at a fixed potential. The materials must have suitable surface atomic configuration and adsorption energy for best efficiency. The best way of achieving this is the rational design of active sites. We study the following reactions: carbon dioxide electrochemical adsorption and reduction, electrochemical organic synthesis, and water splitting reaction (or water electrolysis).

The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you’ve not fooled yourself, it’s easy not to fool other scientists. You just have to be honest in a conventional way after that.
— Richard P. Feynman (1974, Caltech)
