摘要：
A facile method to prepare Pt-Ti intermetallic nanoparticles supported on carbon was developed. Starting from a commercial Pt/C catalyst, TiO2 layers were formed on the Pt/C then thermal annealing under a reducing condition successfully produced intermetallic Pt-Ti nanoparticles with an average size of 4.2 nm. The intermetallic Pt-Ti/C showed enhanced activity and durability for oxygen reduction reaction due to the change in electronic structure and less aggregation. (C) 2016 Elsevier B.V.
