2 S1. Calculation of the parameters of ORR The electron transfer number (n) in ORR can be calculated based on the Koutecky-Levich equations (S1-4) at different electrode potentials: 33 1/J = 1/J k +1/J L = 1/J k + 1/Bω 1/2 (S1) B = 0.2nFC o (D o ) 2/3 υ -1/6 J k = nfkc o J L= 0.2nFC o (D o ) 2/3 υ -1/6 ω 1/2 (S2) (S3) (S4) where J, J k, and J L are the total current density, kinetic- and diffusion-limiting current densities, respectively. ω and n are the angular velocity and electron transfer number in ORR, respectively. F (96485 C mol 1 ) is the Faraday constant. C o and D o are the bulk O 2 concentration of ( mol cm 3 in 0.1 M of KOH) and O 2 diffusion coefficient ( cm 2 /s in 0.1 M of KOH), respectively. ν and k are the kinematic electrolyte viscosity (0.01 cm 2 s 1 ) the electron transfer rate constant, respectively. The H 2 O 2 yield and the electron transfer number (n) were calculated by the followed Eqs. S5 and 6, respectively: %HO - I r / N 2 = 200 (S5) I + I / N d r I d n= 4 (S6) I + I / N d r where I d and Ir are the disk and ring current, respectively. N is determined as 0.4 from the reduction of K 3 Fe[CN] 6. S-2
