Molybdenum semicarbide Mo2C was synthesized on carbon fibers Carbopon-B-22 by the method of currentless transfer in molten NaCl-KCl-Na2MoO4-Mo salts. The electrocatalytic activity of the Mo2C/C composite material in a hydrogen peroxide solution has been investigated. It was revealed that this composite material is catalytically inactive in an H2O2 solution. The electrocatalytic activity of composite materials Mo2C/C, TaC/C, NbC/C and uncoated carbon fiber in the decomposition of hydrogen peroxide is compared. The method of cyclic voltammetry confirmed the low activity of Mo2C/C in comparison with other composites.
