(a) Methanol crossover effect test of PG and Pt/C upon addition of 3 M methanol after about 10 min in an O2 saturated 0.1 M KOH solution at −0.25 V. (b) Current-time response of TGCN and Pt/C electrodes at −0.5 V in an O2-saturated 0.1 M KOH at a rotation speed of 1600 rpm. Bode (c) and Nyquist (inset is the enlarge spectrum in lower frequency) (d) spectra of TFCN, FGCCN and Pt/C under a sine wave of 5.0 mV amplitude in the frequency range of 100 kHz to 10 mHz.
