Dataset: Visualizing Redox-Driven Metal–Oxide Interface Dynamics in Ni/GDC Electrodes via In-Situ Auger-Meitner Electron Microscopy

Desciption of Data

The data contain

• raw data from DC coulometry including PEIS data under varying biases (coulometry_incl_PEIS.txt)
• batchfit resuls from PEIS measurements using an R-R|C equicalent circuit (Batchfit_NiGDC.txt)
• raw data from electrochemical staircase experiments (electrochemical_staircase_type1.txt and electrochemical_staircase_type2.txt)
• raw data from cyclovoltammetry (cyclovoltammetry_-600_400_mV.txt)
• raw data fron NAP-XPS measurements (NAP_XPS_NiGDC_dewetting.vms)

Context and methodology

• the electrochemical data were aquiered in an UHV in-situ Auger-Meitner electron microscope using a Biologic analyzer at 750 °C.
• NAP-XPS spectra were aquiered under gas phase (CO/CO2, H2/H2O) also at 750 °C.
