Abstract:
The degradation of phenols has become urgent issues. In this paper, the diamond film electrode modified by photochemistry is chosen as the research object for phenol degradation. The boron-doped diamond films, which are modified and unmodified, are characterized by the X-ray photoelectron spectroscopy (XPS). Cyclic voltammograms are used to test the electrochemical window. It is found that the current value of tantalum/boron-doped diamond (Ta/BDD) electrode with amino modification increases two orders of magnitude in degrading the nitro-phenol, when the amino-modified rate is only 1.9%. The current value is enhanced from −4.0 × 10−4A-4.0 × 10−4 A to −4.0 × 10−2A-4.0 × 10−2A. In addition, in order to understand the excellent characteristics of Ta/BDD electrode modified by photochemistry for phenol degradation, the efficiency of degradation is also discussed.
