a Linear sweep voltammetry (LSV) curves, b cyclic voltammograms (CVs) for PtMg/C-31 and commercial Pt/C recorded in O2-saturated solution. c Electrochemically active surface areas (ECSAs) and d mass activities determined at 0.9 V for PtMg/C-31 and commercial Pt/C before and after 30,000 accelerated durability tests (ADT). LSVs recorded before and after the ADT e for PtMg/C-31 and f for Pt/C. Note: All electrochemical measurements were conducted in a 0.1 M HClO4 solution at room temperature. The durability tests were performed according to the DOE protocol described in the Supplementary Information.
