Dynamic Cu Exsolution from SrTiO₃ for CO₂ Hydrogenation

Paul Scherrer Institute · Visiting PhD Research

Operando XPS · in situ XRD · Cu exsolution · Oxygen vacancies · CO₂-to-methanol

This work focuses on understanding the dynamic structural reconstruction of Cu-doped SrTiO₃ catalysts under hydrogen atmosphere. By combining operando XPS, in situ XRD, Autochem, and complementary characterization methods, investigate how oxygen-vacancy formation, Cu exsolution, surface Sr enrichment, and catalyst reconstruction evolve under reaction conditions and collectively govern catalytic behavior.
