Abstract

The anodic oxidation of sulfuric acid to peroxodisulfuric acid has been investigated on boron‐doped synthetic diamond electrodes obtained by hot filament chemical vapor deposition. The results have shown that high current efficiency for peroxodisulfuric acid formation can be achieved in concentrated and using high current densities . The main side reaction is oxygen evolution. A reaction mechanism, involving the hydroxyl radical, also has been proposed. ©2000 The Electrochemical Society
