A02

The A02 group (AK Andronescu) focuses on electrochemical characterization to establish structure–composition–activity correlations. We receive samples from the C04 and C05 groups: C04 provides a library of Co, Fe, Ni, Mn, and Cr oxides, analyzed via Scanning Droplet Cell (SDC) to probe composition–activity relationships, while C05 supplies laser-treated Fe-doped cobalt oxide films, evaluated with Scanning Electrochemical Cell Microscopy (SECCM) for local activity mapping. Complementary SEM, Raman, AFM, and collaborator-provided TEM analyses are performed to support a comprehensive understanding of A02 objectives.
