Platinum dendrites with controlled sizes for oxygen reduction reaction
Platinum dendrites were synthesized with the controlled sizes of 13-53 nm, and their electrocatalytic properties were evaluated for oxygen reduction reaction (ORR). Dendrites showed a superior activity for ORR and better selectivity for the production of H2O, compared to commercial E-tek catalysts. Durability was also tested by estimating the change in electrochemically active surface area (ECSA) after extended periods of oxygen reduction. Dendrites with larger sizes showed improved durability.
