Green Hydrogen Peroxide: Advances of Electrocatalytic Generation and Applications in High‐Value Chemical Conversion

The development of environmentally friendly oxidants has emerged as a prominent topic in the fields of green chemistry and chemical engineering. This review comprehensively examines the sustainable production of hydrogen peroxide (H 2 O 2 ) via electrocatalytic oxygen reduction reaction (ORR) and its applications in green chemical synthesis. H 2 O 2 , known as a green oxidant, is generated through the 2e − ORR pathway using various catalysts, including noble metals, carbon‐based materials, single‐atom catalysts, and transition metal oxides. This method offers an environmentally friendly alternative to traditional H 2 O 2 production, enabling in situ synthesis without organic waste. The review highlights the direct role of H 2 O 2 in promoting chemical transformations, such as the oxidation of alkenes to epoxides and alcohols to carbonyl compounds. Additionally, it explores the indirect application of H 2 O 2 through its decomposition into hydroxyl radicals (•OH) in Fenton reactions, which drive selective oxidation and degradation processes. These applications demonstrate the versatility of H 2 O 2 in advancing green chemistry by facilitating eco‐friendly oxidation reactions and pollutant degradation. Future work focuses on improving catalyst stability and scalability for industrial use, further enhancing the sustainability and efficiency of H 2 O 2 ‐based chemical processes.
