Facile Construction of Pt–Co/CN_<i>x</i> Nanotube Electrocatalysts and Their Application to the Oxygen Reduction Reaction

Abstract

A straight forward method for immobilizing Pt-Co alloyed nanoparticles onto nitrogen-doped CNx nanotubes is presented. The as-prepared electrocatalysts exhibit good performance for oxygen reduction reaction in acidic medium arising from the high-dispersion and alloying effect of the Pt-Co nanoparticles and the intrinsic catalytic capacity of the CNx nanotubes.
