Electrochemical synthesis of sodium peroxycarbonate at boron-doped diamond electrodes
An electrochemical method for the preparation of sodium peroxycarbonate at boron-doped diamond anodes has been described. Effects of experimental conditions such as current density, electrolyte concentration and anode materials on the formation of sodium peroxycarbonate have been investigated. The maximum current efficiency for producing sodium peroxycarbonate was found to be 82% at a current density of 0.05 A cm(-2) after 30 min of electrolysis in a solution of 1 M Na2CO3. The minimum energy consumption was found to be 2.2 Wh g(-1) at a current density of 0.05 A cm(-2). The X-ray powder diffraction pattern was obtained in order to identify the products. The products were also analyzed using TG/DTA in order to determine the melting point. (C) 2003 The Electrochemical Society.
