Under kinetic control employing Fe atom deposition from solution and gas phase monoatomic iron centers will be embedded in N-doped vertically aligned carbon nanotubes (CNTs). Goal is the controlled coordination of iron towards different nitrogen containing groups (pyrrolic, pyridinic) aiming towards formation and characterization of defined FeNx centers which are embedded in an extended carbon framework. These will be studied as single atom catalysts (SACs), e.g. in ORR.
