Elucidating the influences of electrochemically tuned surface composition on the hydrogen evolution reaction at CCSS (C03)

• Subject Area: Synthesis and Properties of Functional Materials
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

In C03 we will modify the surface composition, and hence the SAA, of CCSS samples by electrochemical dealloying and underpotential deposition. While the former is a selective removal of one component from the CCSS, the latter is the addition of a (sub-) monolayer of Cu or Pb on the CCSS and for both cases the extent of modifying is controlled by the transferred charge. We will determine the HER activity of the such modified samples and link activities changes to changes in the SAA, determined in collaboration with other CRC projects.
