Electrochemical oxygen reduction reaction (ORR) for hydrogen peroxide (H2O2) synthesis offers a green alternative to the anthraquinone process, but suffers from low oxygen utilization efficiency and high energy consumption. This study introduces a superhydrophobic natural air diffusion electrode (NADE) enhancing the oxygen diffusion coefficient at the cathode by 5.7 times compared to a gas diffusion electrode (GDE). NADE facilitates natural oxygen diffusion, eliminating the need for oxygen/air pumping, leading to rapid H2O2 production (101.67 mg h⁻¹ cm⁻²) with high oxygen utilization efficiency (44.5%-64.9%). The long-term stability and high current efficiency at high current density suggest NADE's potential for industrial-scale H2O2 electrosynthesis and environmental remediation.
