(a) CV, (b) ORR LSV, (c) H2O2 yield, and (d) electron transfer number of FeDNHT-AT-700HT catalysts. The electrochemical behavior of the prepared catalyst was measured using a three-electrode system. The carbon rod was used as a counter electrode, while Ag/AgCl (3 M Cl- saturated) was used as a reference electrode. CV and LSV were conducted in an N2-saturated KOH and an O2-saturated HClO4 solution, respectively.
