The present invention relates to a method for producing sulfur-doped graphene using electrochemical technique and a bifunctional catalyst including sulfur-doped graphene produced therefrom and, more specifically, to a sulfur-doped graphene producing method which includes: a step (1) of producing mixed solution by adding a sulfur precursor to sulfuric acid solution; a step (2) of mounting graphite foil and platinum (Pt) wire in the mixed solution produced by the step (1); a step (3) of connecting a positive (+) electrode to the graphite foil of the step (2), connecting a negative (-) electrode to the platinum wire, and separating sulfur-doped graphene by applying a voltage of 7-20 V; a step (4) of washing sulfur-doped graphene separated in the step (3); and a step (5) of performing thermal treatment after the step (4). The produced sulfur-doped graphene has a bifunctional catalytic activity in oxygen reduction reaction and oxygen generation reaction.
