The article discusses the current challenges in hydrogen peroxide (H2O2) production and the need for cleaner and more sustainable methods. It focuses on the electrochemical synthesis of H2O2 using single-atom catalysts (SACs) for decentralized onsite production, reducing costs and safety risks. SACs, particularly Fe SACs derived from microbial precursors, show promise in enhancing the oxygen reduction reaction (ORR) and selective H2O2 production. By fine-tuning the coordination environment of Fe SACs, researchers aim to achieve efficient conversion of different ORR products. The study explores the transformation of microbial Fe-dependent proteins into Fe active sites, optimizing catalyst performance for H2O2 production. Through computational analysis, the importance of axial oxygen in FeN3O2 sites during the ORR is highlighted. The research provides insights into the structural design of SACs from microbial sources, demonstrating a significant step towards sustainable and cost-effective H2O2 production.
