Characterization of 2D Catalyst-Interfaces – Correlation of Nanoscale Electrochemical and Structural Properties under in situ/operando Conditions (C04)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation ; Analytical Chemistry ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364549901

C04 will correlate scanning electrochemical probe microscopy with tip-enhanced Raman spectroscopy to provide spatially and temporally resolved information on the light-driven reactivity of model matrices for HER and WOC. Key research targets are studying the effects of local inhomogeneities (e.g., with respect to PS and CAT distribution) on membrane performance as well as exploring degradation mechanisms of matrices and matrix-components on the molecular level. In situ/operando measurements under irradiation will be performed to provide unprecedented insights into the behavior of 2D carbon nanomembranes or nanoporous block copolymer membranes functionalized with molecular PS and CATs.
