AbstractMesoporous carbon spheres (MPCs) are synthesized using a template assisted ultrasonic spray pyrolysistechnique and explored as the support materials for non-noble metal electrocatalysts intended to beused for PEM fuel cell oxygen reduction reaction (ORR). TEM images show that MPCs synthesized are thehoneycomb-like carbon spheres with uniform nanosized pores. MPC's surface area thermal stability andaffinity to catalyst are improved by a second heat treatment and an acidic treatment confirmed by BET TGA and electrochemical measurements respectively. The synthesized Fe-Nxcatalyst with MPC supportshows an improved ORR activity when compared to the catalyst supported by commercially available Black Pearl 2000. © 2013 Published by Elsevier Ltd.
