The aim of this paper is to perform the electrosynthesis of polypyrrole/multi-walled carbon nanotube(MWCNT) nanocomposites with different concentration of MWCNT on graphite cathode for theelectrogeneration of H2O2 by reducing dissolved oxygen. The results show that cathode modified withnanocomposite with 2.5% w/w MWCNT (GPM-2.5) had highest electrocatalytic activity. In addition, amaximum concentration of H2O2, up to 5.6 mg L 1, is achieved under the conditions of0.55 V (vs. SCE)and pH = 3 after 10 min electrolysis. Furthermore, it is demonstrated that the GPM-2.5 cathode has a highefficiency in decolorization of basic blue 41 by electro-Fenton process.
