The study presents a novel method for the indirect synthesis of hydrogen peroxide (H₂O₂) without the use of hydrogen gas, which is typically required in industrial processes. The researchers developed a membrane reactor that enables electrochemically-driven hydrogenation of anthraquinone using water as a hydrogen source. This approach significantly reduces carbon emissions compared to traditional methods that rely on steam-methane reforming for H₂ production. The membrane reactor, which separates an electrochemical compartment from a hydrogenation compartment, allows for high current efficiencies and fast reaction rates. The study demonstrates continuous H₂O₂ synthesis over 48 hours, with a current efficiency of 54 ± 4%. This technology offers a promising pathway for carbon-neutral H₂O₂ production, potentially reducing the environmental impact of industrial processes.The study presents a novel method for the indirect synthesis of hydrogen peroxide (H₂O₂) without the use of hydrogen gas, which is typically required in industrial processes.
