Rotating disk electrode measurements of activity and stability of monolayer Pt on tungsten carbide disks for oxygen reduction reaction

► ORR evaluation of monolayer Pt on WC using disk surfaces. ► Monolayer Pt/WC show lower ORR activity over bulk Pt. ► W-oxidation under Pt monolayer in O 2-saturated environment affects ORR activity. In the current study, rotating disk electrode measurements were performed to gain insight into the o...
