Operando x-ray spectroscopy of the oxygen evolution reaction
Research
Operando x-ray spectroscopy is one of most powerful techniques to investigate the catalytic mechanism and the accurate identification of active sites in (electrochemical) heterogeneous catalysis. 3d transition metal (hydro)oxides like La(Sr)TMO3 (TM = Fe, Co, Ni and Mn), are actively investigated in relation to replace 5d based systems (e.g., Pt). The interface is critical for high performance due to its highly disordered structure differing from the bulk phase. In this project, we plan to conduct experiments for OER and ORR using operando x-ray spectroscopy. We combine (near) atomic spatial resolution to characterize catalysts under different levels conditions.
