Abstract

A straight forward method for immobilizing Pt–Co alloyed nanoparticles onto nitrogen-doped CNx nanotubes is presented (see image). 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.
