AT THE
INTERFACE
OF DISCOVERY.

Led by Dr. Weiran Zheng, we study how electrochemical interfaces evolve during water electrolysis and ammonia oxidation. We combine operando spectroscopy, electrochemical microscopy, and time-resolved impedance analysis to connect surface changes with activity, selectivity, and degradation.

We also develop quantitative methods, including dynamic iR correction, for reliable evaluation of catalysts and electrode materials.
