Leader

Dr. Olga V. Safonova (PSI)

ESRs

1, 2, 7, 8, 9, 10, 11, 12, 14

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
