The invention provides a metal-free boron-doped-charcoal-material hydrogen peroxide (H2O2) electroreduction catalyst and a preparation method thereof. The method comprises the steps of uniformly mixing triphenyl borane and a charcoal material according to the mass ratio of (3-5):(97-95), milling the mixture for 3-5 hours in a ball mill at the speed of 3,000-5,000r/min, putting the milled mixture in a heating furnace, firstly introducing argon gas for 10 minutes, reacting for 5-6 hours at the temperature of 750-850 DEG C under the protection of the argon gas, and cooling to room temperature under the protection of the argon gas, thereby obtaining the metal-free boron-doped-charcoal-material H2O2 electroreduction catalyst. According to the metal-free boron-doped-charcoal-material H2O2 electroreduction catalyst and the preparation method thereof, a B-C bond is formed through substituting carbon with electron-deficient boron, and superfluous positive charges are generated nearby a boron atom, so that H2O2 adsorption is facilitated; the raw materials are wide in source and are cheap; the boron-doped activated charcoal catalyst is high in electrochemical activity, good in stability and strong in toxicity resisting capability; due to the absence of precious metals or transition metals, the occurrence of H2O2 hydrolysis reaction can be inhibited, and the generation of oxygen gas is reduced; the electro-oxidation property and utilization ratio of H2O2 are greatly improved.
