Abstract: N-doped carbon nanotube (NCNTs) with highly loaded metal catalysts (Fe/Ce-NCNTs) were synthesized via high-temperature pyrolysis method with Fe-based catalysts introducing Ce metallic. Ce metal can better promote the growth of carbon nanotubes (CNTs), anchoring more iron atoms and increasing the number of Fe—NX active sites. A highly conductive 3D network structure facilitates oxygen diffusion, electron transfer, and transport of reac-tion products. The Fe/Ce-NCNTs catalysts exhibited good catalytic activity (the half wave potential was 0.86 V (vs RHE)) and stability in alkaline media. Moreover, the assembled Al-air batteries (AABs) with Fe/Ce-NCNT exhibited a high performance with a power density of 142 mW·cm-2 and discharge specific capacity of 865 mAh·g-1 at 50 mA· cm-2. Fe/Ce-NCNTs possessed high voltage under a high current density load.
