Anodic oxidation of 4-chlorophenoxyacetic acid on synthetic boron-doped diamond electrodes

Abstract: The anodic oxidn. of 4-chlorophenoxyacetic acid (CPA) on synthetic B-doped diamond thin film electrodes in acid media was studied, using cyclic voltammetry and bulk electrolysis. The results showed that in the potential region where the supporting electrolyte is stable, reactions occur, resulting in the loss of activity due to electrode fouling. Electrolysis at high anodic potentials in the region of electrolyte decompn. causes complex oxidn. reactions that lead to the complete incineration of CPA. There is no indication of electrode fouling under these conditions. The exptl. were compared with a theor. model. This model is based on the assumption that the electrochem. oxidn. of CPA by electrogenerated hydroxyl radicals is a fast reaction and that the process is diffusion-controlled. [on SciFinder (R)]

Properties of diamond electrodes for wastewater treatment

Abstract: B-doped diamond films were deposited by large-area hot filament chem vapor deposition (HFCVD) on Si and different industrial electrode materials, such as Ti, Zr, Nb, Ta, W, and graphite, with areas up to 50 * 60 cm2 B-doping levels ranging from 50 to several thousand ppm were realized using trimethylborate These electrodes are characterized in terms of their material and electrochem properties by SEM, Raman spectroscopy, secondary ion mass spectrometry (SIMS), and cyclic voltammetry Oxidn of org compds in water was studied using different alcs and org acids In the presence of O2, org mols were oxidized even at very low concns to CO2 in the absence of large amts of other detectable byproducts [on SciFinder (R)]

Electrochemical behavior of synthetic boron-doped diamond thin film anodes

Abstract: The electrochem. behavior of some model org. compds. on boron-doped synthetic diamond thin film electrodes, obtained by HF-CVD on p-Si substrate was investigated. Only reactions involving simple electron transfer like hydroquinone/benzoquinone are active in the potential region of the supporting electrolyte stability, although this system is irreversible on diamond electrodes. For oxidn. reactions with more complex mechanism, diamond electrodes show no electrocatalytic activity in the potential region of the supporting electrolyte stability. These complex oxidn. reactions can take place on diamond electrodes in the potential region of the supporting electrolyte decompn. The reactivity of some alcs. and carboxylic acids is studied by cyclic voltammetry. Isopropanol in 1 M H2SO4 is oxidized on diamond anode at a const. c.d. and the intermediates formed are analyzed by HPLC. Finally, a simplified mechanism for the oxidn. of orgs. by electrogenerated OH radicals on diamond is proposed. [on SciFinder (R)]

Recent advances in diamond-like carbon films in the medical and food packing fields

Abstract: due to their outstanding properties such as high hardness, chemical inertness, and high electrical resistivity. The mechanical properties of DLC fall between those of graphite and diamond; the material possesses low-friction coefficient, low wear rate, high hardness, excellent tribological properties, and good corrosion resistance. DLC is an excellent candidate for use as biocompatible coatings on biomedical implants, which is due to not only its excellent properties but also its chemical composition containing only carbon and hydrogen, which are biologically compatible with human cells.
