The Graphitization-Stability Relation of High Surface Area Carbons
This work focuses on how the overall catalyst durability depends on morphological and chemical properties of the catalyst support material. Morphological and chemical changes have been induced in a high surface area carbon by heat treatment at different temperatures. The resulting samples, along with the pristine material, have been characterized by Raman spectroscopy, XRD and XPS. Furthermore, all these support materials have been platinized and tested for activity in the oxygen reduction reaction as well as their stability under potential cycling in acidic environment The degradation was done according to the FCCJ degradation protocol and took place in a two compartment – three electrode cell setup.
