Related Articles

Abstract

In order to improve the electrochemical activity of anode in the electrochemical regeneration of acidic cupric chloride etchant, the graphic felt anode is doped with nitrogen using urea. X-Ray photoelectron spectroscopy (XPS) and Fourier transformation infrared spectroscopy (FT-IR) are performed to characterize the elements and functional groups on the graphic felts. The results show that the nitrogen content of graphic felt increases by 2.68%. Cyclic voltammetry (CV) and linear sweep voltammetry (LSV)are adopted to investigate the electrochemical properties of the graphic felt. The graphic felt treated in 700 ℃ for 12 h exhibits the best electrochemical activity toward Cu(I) oxidation.
