摘要

Gas diffusion electrodes modified with redox catalysts, process and eletroquu00ecmico su00ecntese reactor of hydrogen peroxide using the same. The present invention relates to a process for the synthesis of hydrogen peroxide in media with different pH values, the gaseous diffusion electrodes modified with redox catalysts and a device for the electrolytic reaction.More specifically, the present process compreendende stages the passage of electrical energy (electrical current and / or electric potential) in an electrolytic aqueous solution between cathode and anode.To promote the reaction of reduction of molecules of oxygen gas (02) to hydrogen peroxide (H ~ 2 ~ ~ 2 ~ or ho ~ 2 ~), the use of gas diffusion electrodes (EDG) modified with organic redox catalysts, or functional equivalent, as a cathode, independent of the material empregad As anode, in the synthesis of hydrogen peroxide.From the reaction of reduction of the oxygen gas (~ 2 ~); and the use of gas diffusion electrodes (EDG) modified, at the same time, from the oxidation reaction of the water in the anode.The present invention relates to the design, construction and operation of equipment known as electrochemical reactors, or electrolyte using gaseous diffusion electrodes modified with organic redox catalysts or not, or functional equivalent, as a cathode, or Rranjos thereof, to promote the synthesis of hydrogen peroxide.
