Objective

To physically characterize the clusters arrays as prepared and under realistic thermo- and electrocatalytic
reaction conditions.

Tasks
Task 2.1. Ex-situ characterization
  • Structure and morphology of the deposited clusters studied by AFM, STM, AES, and RBS (KUL)
  • Electronic properties of selected cluster systems investigated by XPS (KUL)
  • Detailed study of the atomic structure and morphology of the clusters and the influence of the substrate with aberration-corrected scanning transmission electron microscopy (TEM) and/or STM (UA-KUL-DTU)
Task 2.2. In-situ characterization
  • Operando IR-VIS SFG spectroscopy and PM-IRRAS and DRIFTS (RU-PSI-KUL)
  • In situ XAFS using in-house cells at SuperXAS beamline of Swiss Light Source (SLS at PSI) and ESRF (KUL)
  • In-situ TEM under reactive environments (UA)
Sub-task 2.2.1. TCs investigation
Sub-task 2.2.1. ECs investigation
