Operando Photoelectron Spectroscopy

State-of-the-art technique for measuring electron binding energies under real reaction conditions.

Polaron Formation

Local charge centers that form on titanium dioxide semiconductor surfaces when electrode potential is applied. These are charged defects that activate the hydrogen evolution reaction.

Titanium Dioxide (TiO2) Semiconductor Electrodes

Semiconductor material used as a prototype in this research for hydrogen evolution. TiO2 is abundant, low-cost, and more sustainable than platinum-based alternatives.
