Conductive diamond: synthesis, properties, and electrochemical applications

Abstract

This review summarizes systematically the growth, properties, and electrochemical applications of conductive diamond.

Electrochemical Technologies for Detecting and Degrading Benzoquinone Using Diamond Films

“…Among those processes, the electrochemical oxidation (EO) has been the most employed method for treating organic pollutants applying different electrocatalytic materials . Boron‐doped diamond (BDD) anodes are widely used in EO due to their important characteristics that stand out from conventional electrodes, as well as their application to electro‐synthesize oxidants or compounds of high added value . In addition, its greater O 2 overpotential promotes the electrogeneration of higher amounts of physical adsorbed .…”

Nature, Mechanisms and Reactivity of Electrogenerated Reactive Species at Thin‐Film Boron‐Doped Diamond (BDD) Electrodes During Electrochemical Wastewater Treatment

“…[4,[15][16][17][18][19] Thin-film boron-doped diamond electrode is considered as a "non-active" electrode with high oxygen evolution overpotential and huge capacities for the production of large quantities of weakly adsorbed hydroxyl radicals, which can nonselectively oxidize any class of organic pollutants. [24] Several companies across Europe, China, Japan and America are producing this electrode on commercial/industrial scales for different electrochemical applications such as chemical and biochemical sensors, environmental catalysis, electrosynthesis, and energy storage and conversion. [1,11] Thin film BDD electrodes are produced by chemical vapor deposition technology, which is a well-developed and licensed technology.…”

“…[11,[20][21][22][23] This electrode has many distinguish properties such as excellent corrosion resistance and chemical stability, high wear resistance, excellent electrical conductivity and electrochemical properties as well as low surface reactivity towards the generated radicals. [24] For electrochemical wastewater treatment application, proper selection of substrate on which the thin film of BDD is deposited is imperative to ensure optimum electrochemical performance and abrasion resistance of the electrode.

Trends in Synthetic Diamond for Electrochemical Applications

“…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 . Analytical chemistry applications include pH sensors, 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 .…”
