Titanium dioxide-supported non-precious metal oxygen reduction electrocatalyst

Abstract

A new non-precious metal oxygen reduction catalyst was developed via heat treatment of in situ polymerized polyaniline onto TiO2 particles in the presence of Fe species. The TiO2 provides for improved performance relative to a carbon black-based catalyst and, at a high catalyst loading, allows for reducing the performance gap between non-precious-metal catalyst and Pt/C to ca. 20 mV in RDE testing.
