3D boron doped carbon nanorods/carbon-microfiber hybrid composites: synthesis and applications in a highly stable proton exchange membrane fuel cell

Boron-doped carbon nanorods (BCNRs) were directly grown on carbon-microfiber by the spray pyrolysis chemical vapour deposition method. The stability of the deposited Pt nanoparticles was found to be increased by more than three times with substitutional boron dopants in 3D carbon nanomaterials. Our work will be of great technological significance for developing highly stable electrode materials in fuel cells.
