Study Co-based Fischer-Tropsch Synthesis (FTS) catalysts by synchrotron-based microscopy and spectroscopy techniques to unravel the activation and deactivation mechanisms. In situ/operando Scanning Transmission X-ray Microscopy (STXM) is used for the elemental mapping of the Co, O, Ti and C on single catalyst particles. Operando hard X-ray Absorption Spectroscopy (XAS) is used to follow long-term activation and deactivation mechanisms of the Co particles via the X-ray Absorption Fine Structure (XAFS).
