Preparation and characterization of carbon black diamond composite electrodes for anodic degradation of phenol

Carbon black diamond (CBD) composite electrodes have been prepared with different percentages of carbon black (5 (5CBD), 20 (20CBD) and 40 (40CBD) as the conductive agent. This article reports for the first time the electrochemical behavior of CBD electrodes. The electrochemical properties of these...
