摘要: 为提高电芬顿(Electro-Fenton)体系H2O2的产率, 制备了多壁碳纳米管(MWNT)电极, 并与石墨/气体扩散(GDC)电极进行了比较. 结果表明, MWNT电极H2O2产率高于GDC电极. 采用电沉积方法, 制备了Fe修饰MWNT(Fe-MWNT)电极, 发现Fe对MWNT电极的修饰不仅可以提高体系的H2O2产率, 而且电流效率可以提高8%左右, 与GDC电极的电流效率接近. Fe-MWNT电极有望成为一种新型的阴极材料应用于Electro-Fenton体系中.

Abstract: To improve the production efficiency of hydrogen peroxide in Electron-Fenton system, multi-walled carbon nanotube (MWNT) electrode was prepared. Compared with graphite/gas diffusion cathode (GDC) electrode, the MWNT electrode showed higher hydrogen peroxide production efficiency. The Fe-modified MWNT (Fe-MWNT) electrode was prepared using the electro chemical deposition method. The as prepared Fe-MWNT electrode showed higher hydrogen peroxide production efficiency, and the average current efficiency increased by 8%after Fe modification in comparison with the unmodified MWNT. The average current efficiency of the Fe-MWNT electrode was close to that of the GDCelectrode. The Fe-MWNT electrode is a novel promising cathode material for application in the Electron-Fenton system.
