“…The resulting catalyst powders contain FeN 4 centers that are attributed as active sites. However, the reports on the nature of the coordinating nitrogen ligands, i.e., pyrrolic or pyridinic, differ as well as the discussion of their contribution toward degradation . On top of this, the pyrolysis process also generates inorganic side phases alongside the desired moieties. Side phases can be of metallic, carbidic, nitridic, or oxidic nature. , These undesired side phases can leach out during FC operation, and the resulting iron ions can further accelerate the degradation, e.g., by Fenton’s reaction and formation of radical oxide species (ROS) . Choi et al observed iron leaching from a ZIF-based FeNC catalyst synthesized solely by pyrolysis.…”
