One-dimensional (1D) Pt-based electrocatalysts demonstrate outstanding catalytic activities and stability toward the oxygen reduction reaction (ORR). Advances in three-dimensional (3D) ordered electrodes based on 1D Pt-based nanostructure arrays have revealed great potential in addressing the mass transfer and durability challenges of Pt/C nanoparticle electrodes for developing high-performance proton exchange membrane fuel cells (PEMFCs). This paper reviews recent progress in the field, with a focus on 3D ordered electrodes based on self-standing Pt nanowire arrays. Nanostructured thin-film catalysts are discussed along with electrodes from Pt-based nanoparticles deposited on arrays of polymer nanowires, carbon, and TiO₂ nanotubes. Achievements on electrodes from Pt-based nanotube arrays are also reviewed. The importance of size, surface properties, and the distribution control of 1D catalyst nanostructures is indicated. Finally, challenges and future development opportunities are addressed regarding large electrochemical surface area (ECSA) and quantification of oxygen mass transport resistance for 1D nanostructure array electrodes.
