In Situ Electrochemistry 原位电化学

understand real time electrochemistry: seeing is believing

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

Rational Electrocatalysis Design 电催化剂设计

develop better catalyst: faster, higher, stronger

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

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)
