• the future, a broader electrochemical study of our Pt/CNW catalysts is required to further uncover the relations between particle embedding, ECSA, utilization, and ORR activity. From the results of the ECSA, ORR, and accelerated stress test measurements, we find CV1 and CV2 to be the most promising
