The synthesis and characterization of pyrolyzed carbon-supported transition metal/nitrogen (M-Nx/C) material based on FeCo alloy and Polypyrrol as source of N atoms are presented. Two different synthetic protocols, a multi-step and a novel one pot single-step approach are compared. In both approaches two different Fe:Co ratio (50:50 and 75:25) were used to obtain Pt-free FeCo-Polypyrrole nanocomposites supported on porous carbon (FeCo/Ppy@C).
