Oxygen reduction reaction (ORR), a key reaction that drives the operation of fuel cells and metal-air batteries, is known for the sluggish kinetics, and catalyst is required for practical applications of ORR. Carbon doped with light elements (especially N and B) is a promising non-noble ORR catalyst. When dopant substitutes carbon atom in graphite lattice, active sites with high electron density are generated either on the dopant atom itself or on the neighboring carbon atoms [1]. Such materials are normally prepared from porous graphite oxide, by treating it with dopant precursors at high temperature [2]. It’s often challenging to characterize such samples in terms of doping level, as dopant atoms present in various forms, including surface contaminations. Moreover, common synthetic routes introduce structural defects. That hinders the possibility to evaluate the performance of the catalyst coming solely from substitutional doping. Thus, there is a discrepancy in the literature regarding the measured ORR kinetics on doped carbon materials. We use epitaxial graphene as a model carbon electrode with perfect planar morphology and composition easily controlled by the XPS and NEXAFS techniques, to evaluate the ORR kinetics in aprotic media on graphene with various types of doping. We compared the ORR kinetics on N-, B- and undoped epitaxial graphene grown by CVD on Ni(111), Ir(111) single crystals and Cu foil. For the evaluation of ORR kinetics, oxygen-saturated 0.1 M solution of tetrabutylammonium perchlorate (TBAP) in dimethylsulfoxide (DMSO) was chosen as electrolyte, as DMSO is common solvent for metal-air batteries due to its relative chemical stability and high solvation ability. To determine the ORR rate constant on the graphene electrodes, the Nicholson approach for quasireversible electron transfer reactions was utilized [3]. By comparing the variation of peak-to-peak separation with the sweep rate with known tabulated values [3], electron transfer rate constants were determined for doped graphene electrodes and compared to undoped one. It was found that ORR is accompanied by the following irreversible chemical step. Rate constants for both electrochemical and chemical steps were calculated using DigiElch CV-simulation package. It was found that N-doped graphene exhibits 2 times higher electron transfer rate constant than undoped one, and the rate of the chemical step is insensitive to the electrode material.
