Abstract

According to various aspects of the present disclosure, a catalyst for rechargeable energy storage devices having a first transition metal and a second transition metal, wherein the first and second transition metals are formed on carbon nanotubes, the carbon nanotubes are doped with nitrogen and phosphorous, wherein the carbon nanotubes have edges and interlayer spaces and are axially aligned, and the first and second transition metals form bimetal centers, wherein the bimetal centers may be uniformly distributed catalytic active sites located at the edges or the interlayer spaces of the carbon nanotubes providing intercalated layers. The present FeCo—NPCNTs are a morphology-dependent catalyst that provides effective performance for bifunctional oxygen reduction reaction and oxygen evolution reaction in metal-air-cells and fuel cells.
