Advanced oxidation processes (AOPs) represent one of the most powerful strategies for dealing with the ever-growing water pollution problem. However, their application is hindered by high cost and risk of handling catalysts and sacrificial chemicals, as well as the low efficiency of electron transfer to peroxides. Here, we report that the addition of nanoparticles (NPs) into the electric field facilitates electron transfer on the surface of NPs to generate reactive oxidizing species (ROS) without the use of sacrificial chemicals. Electrostatic induction can drive the charge separation of individual NPs. Because of the polarization, NPs are turned into numerous bipolar electrodes, which activate the electrogenerated H₂ and O₂ to form ROS, thereby efficiently enabling their fast reaction with the adjacent pollutants. This discovery may provide a general methodology that is fundamental for AOPs and has wide applications for real-life water remediation.

先进的氧化工艺（AOP）代表了解决不断增长的水污染问题的最有效策略之一。然而，它们的应用受到高成本和处理催化剂和牺牲化学品的风险以及电子转移至过氧化物的低效率的阻碍。在这里，我们报告说，在电场中添加纳米颗粒（NPs）有助于电子在NPs表面上转移，从而在不使用牺牲性化学物质的情况下产生反应性氧化物质（ROS）。静电感应可以驱动单个NP的电荷分离。由于极化，NP被转变为许多双极电极，从而激活了电生成的H ₂和O ₂形成ROS，从而有效地使其与相邻污染物快速反应。这一发现可能提供了一种通用的方法，这对于AOPs是基本的，并且在实际的水修复中具有广泛的应用。
