Electrochemical oxidation of water on synthetic boron-doped diamond thin film anodes
TLDR
In this article, a simplified mechanism involving hydroxyl radicals formed by water discharge has been proposed for water oxidation on boron-doped diamond anodes, where small amounts of O3 and H2O2 are formed.Abstract:
Electrolysis in aqueous 1 M HClO4 and 1 M H2SO4 solutions has been carried out under galvanostatic conditions using boron-doped diamond electrodes (BDD). Analyses of the oxidation products have shown that in 1 M HClO4 the main reaction is oxygen evolution, while in H2SO4 the main reaction is the formation of H2S2O8. In both electrolytes small amounts of O3 and H2O2 are formed. Finally, a simplified mechanism involving hydroxyl radicals formed by water discharge has been proposed for water oxidation on boron-doped diamond anodes.read more

Electrocatalysis in the electrochemical conversion/combustion of organic pollutants for waste water treatment
TL;DR: In this article, a simplified mechanism for the electrochemical oxidation or combustion of organics is presented according to which selective oxidation occurs with oxide anodes (MOx) forming the so-called higher oxide MOx+1 and combustion occurs with electrodes at the surface of which OH radicals are accumulated.
