| 摘 要： | 将碳纳米管固定化制成多孔疏水性导电薄膜构建电化学阴极还原体系，实现过氧化氢在阴极的原位产生。电极特性研究表明，电极在较宽的电压范围内均具有较好的活性。考察了阴极电位、电极成分、氧气流量和电解质浓度对过氧化氢原位产生的影响，在优化条件下经过120 min后过氧化氢达到66.17 mg/L，并探讨过氧化氢原位产生的机理。在此基础上考察原位过氧化氢氧化工艺下对亚甲基蓝的脱色效果，并分析其脱色机理。

| Abstract: | Carbon nanotubes was immobilized into porous hydrophobic conductive thin film to construct the electrochemical cathodic reduction system construction, so as to realize the in-situ generated hydrogen peroxide in cathode. The studies of electrodes characteristics show that the electrode has good activity in a wide voltage range. The effects of cathode potential, electrode composition, and oxygen flow rate and electrolyte concentration on the production of in situ generated hydrogen peroxide were evaluated. The concentration of hydrogen peroxide is up to 66.17 mg/L when the reaction time is 120 min under the optimized conditions. The mechanism of in situ generated hydrogen peroxide was also investigated. On this basis, the effectiveness of in-site hydrogen peroxide oxidation process in the decolorization of wastewater containing methylene blue was evaluated, and the decolorization mechanism was analyzed. |
