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)
Electrochemistry represents a significant aspect of modern physical chemistry, especially related to current energy topics. It is the art of playing the potential to control electrons to break and form bonding. You can find resources for fundamental electrochemistry here.
Our group adopts the research logic of Understand, Design, Integration, including the following topics:
Surface detection of electrocatalyst using in situ technique: Raman, AFM, ATR-IR, and UV-vis spectroscopy
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 scanning electrochemical microscopy (AFM-SECM) 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 fix potential. For best efficiency, the materials need to have suitable surface atomic configuration and adorption energy. The best way of achieving this is 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).
Electrochemical synthesis of inorganic materials
Single atom catalysts for water splitting reaction, CO2 reduction reaction, biomass conversion
Electrochemical exfoliation and doping of layered materials for electrocatalysis
