Production method of gas diffusion electrode for hydrogen peroxide su00ecntese eletroquu00ecmica

摘要

Method of production of gaseous diffusion electrodes for su00ecntese eletroquu00ecmica of hydrogen peroxide.The present invention relates to a method for the production of gaseous diffusion electrodes modified with or without redox catalysts.For the electrochemical synthesis of hydrogen peroxide in aqueous medium with different pH values, comprising the steps of: preparing gas diffusion electrodes (EDG)Modified or not with redox catalysts, from a sintering process of a variable mixture of a hydrophilic phase composed of pigments grafu00edticos drivers.And redox catalysts, and a hydrophobic polymer phase, acting as a binder, deposited on a substrate conductor; production of gas diffusion electrodes (EDG)Whether or not containing organic catalysts that can be regeneration in the presence of protons formed, at the same time, from the oxidation reaction of the water in the anode.As cathode in electrochemical cells or reactors; and production of gas diffusion electrodes (EDG) to be used as cathodes, regardless of the material used as anode.In the synthesis of hydrogen peroxide from the reduction reaction of oxygen gas (~ 2 ~).
