Electrooxidation of the Reactive Orange 16 Dye Using Boron Doped Diamond and DSA Type Electrodes

Porous boron-doped diamond/carbon nanotube electrodes.

Nanostructuring boron-doped diamond (BDD) films increases their sensitivity and performance when used as electrodes in electrochemical environments. We have developed a method to produce such nanostructured, porous electrodes by depositing BDD thin film onto a densely packed "forest" of vertically aligned multiwalled carbon nanotubes (CNTs). The CNTs had previously been exposed to a suspension ...

PHENOL REMOVAL FROM WASTEWATERS BY ELECTROCHEMICAL OXIDATION USING BORON DOPED DIAMOND (BDD) AND Ti/Ti0.7Ru0.3O2 DSA ELECTRODES

Industrial wastewater containing non-biodegradable organic pollutants consists of highly toxic effluents whose treatment is necessary due to environmental and economical restrictions. In order to treat these effluents, an electrochemical process using a dimensionally stable anode (DSA) and boron-doped diamond (BDD) electrode was studied. The performance of these electrodes for COD removal from ...

Treatment of Pharmaceutically Active Compounds by Electrooxidation Using Boron Doped Diamond and Platinum Anodes

The Water Decomposition Reactions on Boron-Doped Diamond Electrodes

As reações eletródicas que ocorrem em ambos extremos da extensa janela eletroquímica do eletrodo de diamante dopado com boro foram analisadas por curvas de polarização visando determinar as respectivas energias de ativação aparentes para a etapa determinante da velocidade em cada caso. Encontrou-se que a reação de desprendimento de hidrogênio ocorre por um mecanismo VolmerHeyrovsky, com a prime...

Application of Boron-doped Diamond Electrodes for Wastewater Treatment

Boron-doped diamond (BDD) thin film is a new electrode material that has received great attention recently because it possesses several technologically important characteristics such as an inert surface with low adsorption properties, remarkable corrosion stability, even in strong acidic media, and an extremely wide potential window in aqueous and non-aqueous electrolytes. Due to these properti...
