Photocatalytic Reaction Mechanisms

Solid-state NMR and EPR techniques are utilized to investigate the microscopic structure of catalysts, revealing catalytic active sites and establishing structure-activity relationships. By integrating in-house developed in situ and operando methods, the aim is to achieve real-time monitoring of photocatalytic reactions. This capability enables the capture of reaction intermediates, facilitating the elucidation of the mechanisms that govern photocatalytic processes.
