Resumen

Hydrogen peroxide (H2O2) is a clean oxidizing reagent with many industrial, environmental, medical, and domestic applications. It has been frequently produced using the anthraquinone oxidation process. However, more recently, the electrochemical production of H2O2 has become a popular alternative, as this process is chemically green and sustainable since it employs abundant and inexpensive starting molecules (O2 and H2O). This review focuses on the electrochemical synthesis of H2O2 using the two-electron water oxidation reaction (2e WOR) and two-electron oxygen reduction reaction (2e ORR), both on boron-doped diamond (BDD) electrodes functioning as an anode or cathode, respectively. This review begins by identifying the important and fundamental characteristics of BDD electrodes, as well as the influence of their chemical and physical properties in the electrochemical production of H2O2. The principles and mechanism of the 2e WOR and 2e ORR are also discussed. In addition, various environmental applications of H2O2 electrochemical production (via the 2e ORR and 2e WOR) are addressed. Finally, the sustainability and costs of BDD electrodes and future strategies to improve BDD performance are considered.
