Understanding the intrinsic nature of carbon edges toward the electrocatalytic reduction of O2 to H2O2 is challenging due to the inevitable coexistence of edges and heteroatom groups. Herein, ten different gradient nanocarbons with well-defined edge topologies and sizes are used as models to investigate the explicit function of each common edge at a mol. level. We suggest that both armchair and zigzag configurations are pos. in H2O2 formation. Direct proportional structure-function relationships between the size/number/areas of edges and the activities are then proposed. Moreover, the dynamic evolution processes and kinetic behaviors of key intermediate products including O2 (ads) and superoxide anion O2-* are monitored with time-resolved IR spectroscopy and simulation calculations Depending on different edge configurations, O2 (ads) and O2-* species show a steep growth trend in the first 7.3 and 10 s and reach equilibrium until 10 and 13.3 s, resp. O2 (ads) + e– ยกรบ O2-* as a possible rate-determining step (RDS) is evidenced by isotopic-labeling studies.
