Defect-Rich Carbon Supported Pt Nanoparticles via Joule Heating for Enhanced Oxygen Reduction

Abstract

Intrinsic defect-rich carbon is prepared via alkali-assisted pyrolysis of C60. Via Joule heating within seconds, this defective carbon yields Pt particles with an ultrafine size of 2.5 nm. Due to the favorable defect-induced electron transfer, this Pt catalyst shows significantly enhanced activity and stability towards alkaline oxygen reduction.
