Abstract. There are challenges in comparing catalyst performance. The most common method is to compare half-wave potentials (E 1/2).This metric has been helpful since it has allowed the platinum-group metal-free (PGM-free) catalyst community to show that the half-wave potential of PGM-free catalysts can compete with platinum catalysts.
