Abstract
In this work, the porous titanium based β-PbO2 electrode with graphene oxide (GO) intermediate layer has been fabricated. The FT-IR results show that GO can be partially reduced after electrophoretic deposition (EPD) process. The SEM and electrochemical characteristics indicate that the uniform and compact GO layer under 60 s EPD time can cover the substrate smoothly and can provide protection for the substrate effectively. The prepared electrode was verified by the cyclic voltammetry (CV) tests. Furthermore, the degradation of 4C-2-NP on electrode surface was observed to follow Pseudo-first-order kinetic equation. The increasing removal rate of 4-Chloro-2-nitrophenol (4C-2-NP) from 79.25 % to 82.52 % confirmed the electro-catalytic activity of the electrode with GO layer.
