In situ synthesis of Pt/carbon nanofiber nanocomposites with enhanced electrocatalytic activity toward methanol oxidation

► A facile in situ method to synthesis Pt nanoparticles on electrospun CNFs. ► Electrospun CNFs are used as catalysts support, which are cheap and easy to prepare. ► The Pt nanoparticles on CNFs present uniform size and good distribution. ► The as-prepared Pt/CNF nanocomposites exhibit high electrocatalytic activity.
