| Abstract: |
| In this study， a paper-based air diffusion electrode （PNADE） was fabricated using filter paper prepared from mercerized bamboo pulp as the electrode substrate， onto which a carbon black （CB） catalytic layer was in-situ coated. The polytetrafluoroethylene （PTFE）/polyvinylidene fluoride （PVDF） composite system was introduced as both binder and hydrophobic modifier， and a low-cost PNADE with tunable wettability and hierarchical pore structure was constructed. The PNADE was applied to the electrocatalytic synthesis of hydrogen peroxide （H₂O₂）， in which the highly selective two-electron oxygen reduction reaction could be efficiently driven by natural oxygen diffusion， without the need for pressurized oxygen supply devices. Furthermore， the effects of functional component mass ratios and coating amounts on the performance of the prepared PNADE were investigated. The results showed that the PNADE prepared with a CB/PVDF/PTFE mass ratio of 3∶3∶2 and a coating amount of 2 mg/cm² exhibited excellent electrocatalytic performance with selectivity for catalytic synthesis towards H2O2 of 72.4%， and after 180 min of reaction， a H2O2 yield of 451 mg/L was achieved. This performance was attributed to the three-dimensional porous network structure of the paper-based air diffusion electrode and the synergistic effect of the stable gas-liquid-solid three-phase interface. |
