Research Interests 
In one sentence, we are interested in the spectroscopic characterization of surface chemical processes. The aim of our research group is to understand the mechanistic steps and to control heterogeneous surface/interface processes, such as alcohol oxidation, CH4 and CO2 dissociation, as well as electrochemical oxidation, on important metal oxide surfaces at near-ambient condition. A novel spectroscopic approach utilizing surface-specific vibrational sum frequency generation (VSFG), ultrafast transient absorption (fs-TA) and an electrochemical impedance spectroscopy (EIS) has been designed.

  • VSFG, a second-order nonlinear process sensitive only to surface and/or interfacial phenomena, will monitor in-situ adsorption, dissociation, oxidation and charge transfer processes at various gas-solid, liquid-solid and solid-solid interfaces. 
  • Ultrafast fs-TA will characterize the dynamics of electron, hole recombination and transfer process on a catalyst modified metal oxide photoanodes.
  • Spectro-electrochemistry approach by combining VSFG, EIS and basic electrochemistry to study the kinetics governing the intercalation and de-intercalation mechanisms at the electrode-electrolyte interface to develop better secondary ion batteries.
