Fig. 6. Detailed electrocatalytic performances of as-prepared catalysts.

Fig. 6

(A) CVs of the DPARH-, DPA-, DP-, and commercial Pd/C catalyst–modified electrodes in 1 M KOH + 1 M ethanol at a scan rate of 50 mV s−1 versus Ag/AgCl (saturated KCl). (B) Chronoamperometric curves of these catalyst-modified electrodes in 1 M KOH + 1 M ethanol at −0.3 V for 2000 s. (C) CVs of these catalyst-modified electrodes in 0.5 M H2SO4 + 0.5 M HCOOH at a scan rate of 50 mV s−1. (D) Chronoamperometric curves of these catalyst-modified electrodes in 0.5 M H2SO4 + 0.5 M HCOOH at 0.1 V for 2000 s. The Pd mass amounts of all the catalysts were about 1 μg in each electrode.
