The efficiency of catalysts is strongly dependent on their surface structures and its chemical state. This project is aiming at the plasma-laser induced modification and creation of microstructured, reactive surfaces that can be used in catalysis. Based on plasma-generated reactive species and the knowledge of generation and destruction mechanisms in the effluent, we tailor density distributions and fluxes of reactive species to surfaces, that are simultaneously (self-organised) structured by laser irradiation. Active and passive optical methods are applied to investigate the plasma kinetics and fluence of reactive species to surfaces. Ex-situ diagnostics complete the picture by investigation the surface properties down to the level of chemical states, its struture and catalytic performance.
