Abstract

This is a Corrigendum for the article entitled “A Defect-rich N, P Co-doped Carbon Foam as Efficient Electrocatalyst toward Oxygen Reduction Reaction”, published in ChemCatChem 2020, 12, 4105-4111, DOI: 10.1002/cctc.202000363. We regret to inform you that part of Experimental Section was not presented correctly. The authors requested corrections to this paper at the proof stage, however the corrections to were not applied. The Editorial office apologizes for this oversight. Please see the following as the corrected version: The electron number (n) transferred per oxygen molecule and kinetic current (jk) for ORR procedure can be extracted from the Koutechy-Levich equation:[46] where j is measured current, jd represents the diffusion-limiting current, jk is the kinetic current and ω is the rotating rate. B is determined from the slope of Koutechy-Levich (K−L) plots according to the Levich equation as given below:[46] where n represents the transferred electron number per oxygen molecule. F is the Faraday constant (F=96485 C mol−1), DO2 is the diffusion coefficient of O2 in 0.1 M KOH (DO2=1.9×10−5 cm2 s−1). υ is the kinetic viscosity (υ=0.01 cm2 s−1). CO2 is the bulk concentration of O2 (CO2=1.2×10−6 mol cm−3). The constant 0.2 is adopted when the rotation speed is expressed in rpm. (CO2=1.2×10−6 mol cm−3). The constant 0.2 is adopted when the rotation speed is expressed in rpm. The yield and n (the number of electrons transferred during ORR) were estimated by the followed equations:[47] where Ir is ring current, Id is disk current and N is current collection efficiency of the Pt ring. N was determined to be 0.40.[18]
