The electrochemical properties of a nitrogen‐incorporated tetrahedral amorphous carbon (ta‐C:N) thin‐film electrode were investigated. Cyclic voltammetry was used to investigate the background current response as a function of potential, scan rate, and electrolyte composition. Cyclic voltammetry and digital simulation were used to determine the heterogeneous electron‐transfer rate constants (ko) for IrCl62−/3−, Fe(CN)63−/4−, ferrocene carboxylic acid, Ru(NH3)63+/2+, and methyl viologen. The results revealed that the background current for the ta‐C:N electrode falls between that of BDD and GC. ko values for all the redox analytes at ta‐C:N were comparable to the values at BDD and GC. ko values were lower for Fe(CN)63−/4−, 10−3 cm s−1, than for the other four redox systems, 10−2–10−1 cm s−1. ko for Ru(NH3)63+/2+ was insensitive to the electrolyte cation (Li+, Na+, K+, and Cs+) at all three electrodes. In contrast, ko for Fe(CN)63−/4− was sensitive to the cation type with the greatest sensitivity seen for the ta‐C:N electrode suggestive of more significant double layer effects. The ta‐C:N electrode supports relatively rapid electron transfer for a wide range of redox systems with formal potentials from ca. 0.9 to −1.0 V vs. Ag/AgCl.

“…Doping diamond nanostructures and nanoparticles with dopants such as N and other atoms will widen their applications such as for electrocalaytic reactions (e.g., oxygen reduction/evolution reaction, CO 2 reduction reaction, etc.). Combination of diamond nanostructures with diamond nanoparticles, or the formation of their hybrid nanocomposites, for example, diamond nanowires based diamond nanoelectrodes, diamond nanoparticles coated diamond nanoelectrodes, will take full advantages of diamond as well as nanoelectrochemistry, leading to more novel concepts and applications [147,148]. For example, on such hybrid nanocomposites, the investigation of diamond electrochemistry and electroanalysis at the nanoscale (e.g., capacitive current at a single nanowire, single molecule detection, etc.…”

Macro-sized diamond films have been widely applied as the electrode for electrochemical and electroanalytical applications. Due to the non-uniform doping in diamond, boundary effects, and the varied ratios of graphite to diamond, only averaged electrochemical signals are detected over the full electrode. The studies of diamond electrochemistry at the nanoscale are thus highly required. In this chapter we overview recent progress and achievements about electrochemical properties and applications of diamond nanostructures and nanoparticles. After a brief introduction of the formation of these nanostructures and nanoparticles, electrochemical behavior of diamond nanostructures (e.g., diamond nanotexures, nanowires, networks, etc.) and nanoparticles (undoped, doped nanoparticles) in the presence/ absence of redox probes is summarized. Their electroanalytical (e.g., electrochemical, biochemical sensing, etc.) and electrochemical (e.g., energy storage using capacitors and batteries, electrocatalysis, etc.) applications are shown. Diamond nanoelectrode array is introduced and highlighted as a promising tool to investigate diamond electrochemistry at the nanoscale as well.

“…The electrogenerated ones have interesting properties associated with the possibility to tune their size and composition . Carbon nanotubes (CNTs) have demonstrated to present additional advantages mainly connected with their high surface‐to‐volume ratio, their unique electronic properties and the presence of edge‐plane like defects that make them a very interesting material for electroanalytical applications . Since 2004, graphene has received enormous attention due to its high thermal conductivity, high electron mobility at room temperature, capacity to maintain high current densities, and easy functionalization, among others .…”

We report the advantages of hybrid nanomaterials prepared with electrogenerated ferrites (MFe2O4; M: Co, Mn) and multi‐walled carbon nanotubes (MWCNTs) or thermally reduced graphene oxide (TRGO) on the electro‐reduction of hydrogen peroxide. Glassy carbon electrodes (GCE) modified with these hybrid nanomaterials dispersed in Nafion/isopropanol demonstrated a clear synergism on the catalytic reduction of reduction of hydrogen peroxide at pH 13.00. The intimate interaction between MFe2O4 and carbon nanomaterials allowed a better electronic transfer and a facilitated regeneration of M2+ at the carbon nanomaterials, reducing the charge transfer resistances for hydrogen peroxide reduction and increasing the sensitivities of the amperometric response.
