Abstract
The oxygen reduction reaction electrocatalyst is a Pt/N/C electrocatalyst that provides an efficient ORR catalyst suitable for use in polymer electrolyte membrane (PEM) fuel cells, for example. The oxygen reduction reaction electrocatalyst is in the form of platinum nanoparticles embedded in a nitrogen-enriched mesoporous carbon matrix, particularly a nitrogen-enriched graphite matrix. The nitrogen-enriched graphite matrix has an average surface area of 240.4 m/g, and the platinum nanoparticles each have an average diameter between 10 nm and 12 nm.
