Abstract
Section titled âAbstractâTrends in synthetic diamond: This Special Collection highlights the current development status of synthetic diamond films and their applications in electrochemistry. Diamond is an extremely stable crystalline form of carbon that is a valuable material in many applications, owing to its unusual physical and chemical properties. For this reason, it has long attracted the attention of scientists and the public. Recently, conductive-synthetic diamond films have been the subject of applications and fundamental research in several fields of the science and engineering.1 Since their introduction into electrochemical research in 1987, doped diamond electrodes have become increasingly popular in a wide variety of applications.2 Their unique properties distinguish them from conventional electrode materials and make many electrochemical processes more attractive or even possible. These electrodes have been the subject of a variety of applications and fundamental research in electrochemistry, making way for the branch now known as the âelectrochemistry of synthetic diamond filmsâ.3 Almost every aspect of electrochemistry has been impacted by the diamond electrode, from instrumental analysis to industrial applications. Diamond films are often the preferred materials in many applications, including the synthesis of chemicals, modification of diamond surfaces, electroanalysis, water disinfection, sensing and destruction of pollutants. Large-scale applications include oxidation of organic compounds in wastewater, photoelectrocatalysis, on-site production of hypochlorite, and production of novel oxidants, such as peroxodisulfate and other peroxygen compounds.2, 4 Analytical chemistry applications include pH sensors,1 electrochemical detectors for liquid chromatography, and micro- and nanosensor arrays for simultaneous detection of multiple analytes. Also in development are biological sensors for a wide variety of biochemicals, and nanoelectrodes for the in vivo detection of neurotransmitters.1, 2, 5, 6 Applications in the field of energy include electroreduction of CO2 and energy storage.1, 7 In addition, novel applications have been performed in organic electrochemistry7, 8 as well as in medical and theoretical chemistry. This Special Collection in ChemElectroChem is devoted to the latest trends in synthetic diamond and the invited papers span a wide range of topics, and include both review-type articles and original research reports on the electrochemical applications of diamond films. The Guest Editors are very thankful to all contributors. Topics include theoretical and fundamental studies, the development of new methods, and analytical assays for various applications. For example, scanning electrochemical microscopy as a powerful and convenient technique for determining surface adsorbed intermediates and water oxidation products. A theoretical-chemistry study has been performed to investigate outer-sphere electrochemical oxidation reactions that occur in solution, and reactions involving adsorbed intermediates with electrogenerated hydroxyl radicals. Manuscript topics also include the use of phosphorus-doped nanocrystalline diamond films for supercapacitors and the mechanisms giving rise to changes in electric double-layer capacitance. Several reports in this Special Collection address electrochemical technologies for wastewater treatment. The Reviews and Minireviews outline state-of-art research in electroanalysis of pharmaceuticals, environmental applications, electro-organic synthesis as well as the nature, mechanisms and reactivity of electrogenerated reactive species produced on diamond films. In this regard, this Special Collection in ChemElectroChem is timely and proper as an important research field in diamond electrochemistry. The future for synthetic diamond films is bright, because the advances in this interdisciplinary area will encourage a close collaboration between chemists, electrochemists, engineers, and other scientists, particularly in the use of these materials as effective and selective electrodes for many electrochemical processes and applications.
