Abstract:
Mechanically resilient mats consisting of overlaid electrospun nanofibers with self-generated TiC crystallites embedded in a carbon matrix are surface-decorated with Pt nanoparticles as a novel electrocatalytic system for oxygen reduction reaction. Electrocatalytic activities (e.g., on-set potential and current density) of Pt are substantially enhanced due to high specific surface area of the support and the synergetic effect of TiC and Pt on electrocatalysis.
