(A) Linear sweep voltammogram carried out in 0.1 M KOH at a scan rate of 0.005 V s−1 at 1600 revolutions per minute (RPM). (B) Linear sweep voltammogram carried out in 0.1 M KOH at a scan rate of 5.0 mV s−1 at different rotating speeds Pd-N-IC-rGO. (C) K-L plots constructed using data from C (insert: number of electrons transferred at different potentials determined from K-L plots).
