Abstract

AbstractHydrogen peroxide (H2O2) plays a pivotal role in advancing sustainable technologies due to its eco‐friendly oxidizing capability. The electrochemical two‐electron (2e−) oxygen reduction reaction and water oxidation reaction present an environmentally green method for H2O2 production. Over the past three years, significant progress is made in the field of carbon‐based metal‐free electrochemical catalysts (C‐MFECs) for low‐cost and efficient production of H2O2 (H2O2EP). This article offers a focused and comprehensive review of designing C‐MFECs for H2O2EP, exploring the construction of dual‐doping configurations, heteroatom‐defect coupling sites, and strategic dopant positioning to enhance H2O2EP efficiency; innovative structural tuning that improves interfacial reactant concentration and promote the timely release of H2O2; modulation of electrolyte and electrode interfaces to support the 2e− pathways; and the application of C‐MFECs in reactors and integrated energy systems. Finally, the current challenges and future directions in this burgeoning field are discussed.
