H(2)O(2)是一种用途广泛、环境友好的化学品，用于水处理，如高级氧化工艺。大批量生产H_2O_2需要大量的能量输入和载体分子的周期性更换，因此广泛应用于蒽醌氧化法。H(2)O(2)生产应根据特定的使用场景进行定制。电化学合成H(2O)O(2)可以替代传统的方法，避免了浓缩、运输和储存过程。在此，我们从一系列铋基氧化物中确定了Bi2WO6：Mo是一种低成本和高选择性的选择，用于双电子水氧化反应生成H(2)O(2)。它可以连续提供H(2O)O(2)，用于原位降解水溶液中的持久性污染物。来自氢(2)的清洁能量也可以在阴极上产生。这种水的裂解产生了H(2)O(2)和H(2)的可持续资源，是环境治理和能源科学的进步。
H(2)O(2)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. H(2)O(2)production should be customized considering the specific usage scenario. Electrochemical synthesis of H(2)O(2)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 H(2)O(2)generation via two-electron water oxidation reaction. It can continuously provide H(2)O(2)for in situ degradation of persistent pollutants in aqueous solution. Clean energy from H(2)can also be produced at the cathode. This kind of water splitting producing sustainable resources of H(2)O(2)and H(2)is an advance in environmental treatment and energy science.
