H₂O₂ is a versatile and environmentally friendly chemical involved in water treatment, such as advanced oxidation processes. Anthraquinone oxidation is widely used for large‐scale production of H₂O₂, which requires significant energy input and periodic replacement of the carrier molecule. H₂O₂ production should be customized considering the specific usage scenario. Electrochemical synthesis of H₂O₂ can be adopted as alternatives to traditional method, which avoids concentration, transportation, and storage processes. Herein, we identified Bi₂WO₆:Mo as a low‐cost and high‐selectivity choice from a series of Bi‐based oxides for H₂O₂ generation via two‐electron water oxidation reaction. It can continuously provide H₂O₂ for in situ degradation of persistent pollutants in aqueous solution. Clean energy from H₂ can also be produced at the cathode. This kind of water splitting producing sustainable resources of H₂O₂ and H₂ is an advance in environmental treatment and energy science.
