Hydrogen is used to power fuel cells. They are more efficient than traditional internal combustion engine vehicles and emit no tailpipe emissions—only water vapor and warm air. For rechargeable metal-air batteries and fuel cells, it is very important to make catalysts that work for oxygen reduction reactions (ORR)[1]. In this work, reduced graphene oxide and nitrogen-doped reduced graphene oxide (N-RGO) with a high nitrogen doping content are synthesized via an electrochemical approach. RGO was synthesized using graphite rods as anode and cathode by the electrochemical exfoliation method with a separation of 1 cm in H2SO4 (0.5 M). The N-doped graphene was also prepared by usin
