| Abstract: | In this work, a proof of concept of a novel reactor design for the in-situ electrochemical production of H2O2 from oxygen reduction reaction is presented for the first time. The innovative design incorporates a venturi-based jet aerator to supply atmospheric oxygen without additional energy consumption to a 3D flow-through modified carbon felt (CF) cathode. Preliminary experiments confirmed that electro-generation of hydrogen peroxide is possible in a system as the one proposed. Comparison with a flow-by cell with a gas diffusion cathode under similar conditions revealed that current efficiency towards hydrogen peroxide accumulation is even higher (72 vs 65% at 1 h) than in the case of the conventional system. Jet aerator stands as a promising oxygen supply thanks to its excellent performance and both low investment cost and energy consumption. Considering all the above, the electrochemical jet cell stands as a rather promising design for the efficient hydrogen peroxide electro-generation. |
