2 ORR Measurements Firstly, 2 mg synthetic Pt 3 M/C catalysts were dispersed into 1 ml water/isopropanol/nafion solution (containing 400 µl water, 550 µl isopropanol and 50 µl 5 wt % Nafion solution) by sonication. 10 µl of the dispersion was dispersed on a glassy carbon rotating ring-disk electrode (RRDE, the ring material is Pt), then dried in air. Prior to ORR test, working electrodes were pre-treated by potential cycling in the range of V (50 mvs -1, 50 cycles) to remove surface contaminant. The electrochemically active surface area (ECSA) was estimated by H upd and CO stripping experiments. For H upd calculation, the average charge of the Pt-hydrogen adsorption/desorption region after correction for double layer charging and assuming the value of 210 µc cm -2 for the oxidation of a monolayer of hydrogen 1-3. For CO stripping voltammetric experiments, CO was absorbed at 0.02 V for 10 min, excess CO in the electrolyte was then purged out with N 2 for 10 min, and then first two cycles recorded at 20 mv s -1 and assuming the value of 420 µc cm -2 for the oxidation of a monolayer of carbon monoxide. RRDE measurements were conducted by liner sweep voltammetry (LSV) from 0.2 V to 1.1 V (5 mv s -1, 1600 rpm), while the potential of ring electrode was held at 1.3 V. The following equations were used to determine the electron transfer number (n) and the hydrogen peroxide yield (%H 2 O 2 ). = 4 +( / ) % =100 2 / +( / ) (1) (2) I D and I R are the disk and ring currents, respectively. N represents the collection 2
3 coefficient of H 2 O 2 on the Pt ring. Kinetic current (I k ) was calculated according to the Koutechy-Levich equations: 1 = (3) =0.62nAFC (D ) / ν (4) in which n is the electron transfer number; F is Faraday's constant (96,485 C mol -1 ); A is the area of the electrode (0:196 cm 2 in this work); D 0 is the diffusion coefficient of O 2 in 0.1M HClO 4 (1: cm 2 s -1 ); ν is the kinematic viscosity of 0.1M HClO 4 ( cm 2 s -1 ), and C 0 is the concentration of molecular oxygen in 0.1M HClO 4 solution ( mol cm -3 ) 4. Accelerated durability test (ADT) were conducted by potential cycling from 0.6 to 1.2 V for 20,000 cycles in an N 2 -saturated 0.1M HClO 4 solution at 50 mvs -1. Specific and mass activities were obtained by normalizing the kinetic current density (calculated from the Koutecky-Levich equation) to the mass and ECSA of Pt, respectively. 3
