In the present work, NRGO and Ag/NRGO catalysts were synthesized using eco-friendly reducing agents. Graphene oxide was prepared as a substrate by electrochemical method. Then, using urea as nitrogen source, it was converted into graphene nitrogen dop under a temperature of 160 ° C and used as a silver bed. The presence of nitrogen in the graphene structure results in a better dispersion of the silver metal on graphene and prevents the accumulation of them. To investigate the catalytic behavior of electrocatalysts, linear scaling voltammetry test was used in alkaline medium for oxygen regeneration reaction. Ag / NRGO showed better catalytic behavior than the NRGO as the bare substrate. It also showed better kinetic behavior than NRGO.
