Since the last decades, non-precious metal catalysts (NPMC), especially iron based electrocatalysts show sufficient activity, potentially applicant in oxygen reduction reaction (ORR), however they only withstand considerable current densities at low operating potentials. On the other hand iron based electrocatalysts are not stable at elevated cathode potentials, which is essential for high energy competence, and its remains difficult to deal. Therefore, via this research a simple approach is demonstrated that allows synthesis of nanosize Fe-doped mayenite electride, [CaAlO]·(e) (can also write as, CAFe:e, where doping level, x = 1) (thereafter, Fe-doped C12A7:e), consist of abundantly available elements with gram level powder material production, based on simple citrate sol-gel method.
