Electrogeneration of Hydroxyl Radicals on Boron-Doped Diamond Electrodes

TLDR
In this paper, the electrogeneration of hydroxyl radicals was studied at a synthetic B-doped diamond (BDD) thin film electrode, where spin trapping was used for detection of hydoxyl radicals with 5,5-dimethyl-1-pyrroline-Noxide and with salicylic acid using ESR and liq. chromatog.
Abstract
The electrogeneration of hydroxyl radicals was studied at a synthetic B-doped diamond (BDD) thin film electrode. Spin trapping was used for detection of hydroxyl radicals with 5,5-dimethyl-1-pyrroline-N-oxide and with salicylic acid using ESR and liq. chromatog. measurements, resp. The prodn. of H2O2 and competitive oxidn. of formic and oxalic acids were also studied using bulk electrolysis. Oxidn. of salicylic acid gives hydroxylated products (2,3- and 2,5-dihydroxybenzoic acids). The oxidn. process on BDD electrodes involves hydroxyl radicals as electrogenerated intermediates.

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.
