Research Abstract

Diamond has discriminative properties, such as electrical insulator and super high hardness material, and diamond plays a greater role not only in jewelry but also in industrial use. Electrochemical formation of diamond has been developed by anodic reaction of carbide ion according to the reaction: C_2^<2-> → 2C + 2e^-. In particular, the effects of applied potential on the carbon morphology and the initial stage of carbon formation were investigated. Polyhedral shape of carbon was obtained at more positive potential than 2.4 V on Au wire. The polyhedral shape of carbon was determined as diamond by Raman spectroscopy. Results of chronoamperometry and SEM observation implied that double layer charging and carbon formation occur simultaneously.
