title: Particle size dependence on oxygen reduction reaction activity of electrodeposited TaO(x) catalysts in acidic media.
abstract: The size dependence of the oxygen reduction reaction activity was studied for TaO(x) nanoparticles electrodeposited on carbon black for application to polymer electrolyte fuel cells (PEFCs). Compared with a commercial Ta2O5 material, the ultrafine oxide nanoparticles exhibited a distinctively high onset potential different from that of the bulky oxide particles.
