Triggered by global water quality safety issues, the research on wastewater treatment and water purification technology has been greatly developed in recent years. The Fenton technology is particularly powerful due to the rapid attack on pollutants by the generated hydroxyl radicals (•OH). However, both heterogeneous and homogeneous Fenton/Fenton-like technologies follow the classical reaction mechanism, which depends on the oxidation and reduction of the transition metal ions at single sites. So even after a century of development, this reaction still suffers from its inherent bottlenecks in practical application. In recent years, our group has been focusing on studying a novel heterogeneous Fenton catalytic process, and we developed the dual-reaction-center (DRC) system for the first time. In the DRC system, H₂O₂ and O₂ can be efficiently reduced to reactive oxygen species (ROS) in electron-rich centers, while pollutants are captured and oxidized by the electron-deficient centers. The obtained electrons from pollutants are diverted to the electron-rich centers through bonding bridges. This process breaks through the classic Fenton mechanism, and improves the performance and efficiency of pollutant removal in a wide pH range. Here, we provide a brief overview of Fenton’s story and focus on combing the discovery and development of the DRC technology and mechanism in recent years. The construction of the DRC and its performance in the pollutant degradation and interfacial reaction process are described in detail.We look forward to bringing a new perspective to continue Fenton’s story through research and development of DRC technology.

受全球水质安全问题的影响，近年来废水处理和净水技术的研究得到了极大的发展。由于产生的羟基自由基（•OH）对污染物的快速侵蚀，芬顿技术特别强大。但是，异质和均质的Fenton /类Fenton技术均遵循经典的反应机理，这取决于过渡金属离子在单个位点的氧化和还原。因此，即使经过一个世纪的发展，该反应在实际应用中仍然遭受其固有的瓶颈。近年来，我们小组一直致力于研究新颖的非均相Fenton催化方法，并且我们首次开发了双反应中心（DRC）系统。在DRC系统中，H ₂O ₂和O ₂可以在富电子中心有效地还原为活性氧（ROS），而污染物则由缺电子中心捕获并氧化。从污染物中获得的电子通过键桥转移到富电子中心。此过程突破了经典的Fenton机制，并在宽pH范围内提高了污染物去除的性能和效率。在这里，我们简要概述了Fenton的故事，并着重介绍了近年来DRC技术和机制的发现与发展。详细描述了DRC的构建及其在污染物降解和界面反应过程中的性能。我们期待通过DRC技术的研究和发展，为Fenton的故事提供新的视角。
