| 中文摘要: |
| 本研究以丝光化竹浆滤纸为电极基底,在其上原位涂布负载炭黑(CB)催化层,并引入聚四氟乙烯(PTFE)/聚偏氟乙烯(PVDF)复合体系作为黏结剂及疏水改性剂,构建具有可调润湿性与多级孔隙结构的低成本纸基空气扩散电极(PNADE);将PNADE用于电化学法催化合成过氧化氢(H2O2),在无加压供氧装置条件下,依靠氧气的自然扩散即可高效驱动高选择性的双电子氧还原反应;进一步探究了功能组分质量比及涂布量对制得PNADE性能的影响。结果表明,CB、PVDF和PTFE的质量比3∶3∶2、涂布量2 mg/cm2条件下制得的PNADE表现出优异的电催化性能,其催化合成H2O2的选择性达72.4%,反应180 min后H2O2产量达451 mg/L,这归因于纸基空气扩散电极的三维多孔网络结构及稳定的气-液-固三相界面协同作用。 |
| 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. |
