Abstract

Copper-dimethylglyoxime complex (CuDMG) modified Copper electrode (Cu/CuDMG) showed a catalytic activity towards cyclohexanol oxidation in NaOH solution. The modified electrode prepared by the dimethylglyoxime anodic deposition on Cu electrode in the solution contained 0.20 M NH 4 Cl + NH 4 0H (pH 9.50) and 1 x 10 -4 M dimethylglyoxime. The modified electrode conditioned by potential recycling in a potential range of-900 ∼ 900 mV vs. Ag/AgC1 by cyclic voltammetry in alkaline medium (1 M NaOH). The results show that the CuDMG film on the electrode behaves as an efficient catalyst for the electro-oxidation of cyclohexanol in alkaline medium via Cu (III) species formed on the electrode.
