“…NDs have been applied in electrochemistry by sintering ND powder (Novoselova et al 2004), preparing electrodes by binding the ND powder with mineral oil and immobilising a thin layer onto a glassy carbon electrode (Holt et al 2008), and drop casting from an ethanol solution (Holt et al 2008, Holt 2010. Previous experiments with oxidized and hydrogenated NDs demonstrate that the oxidised particles (including the untreated particles) show increased redox activity in comparison to the hydrogenated powder (Holt et al 2008).…”

“…Different types of nanodiamond with varying surface termination have been investigated for electrochemical activity. [1][2][3][4][5] Most commonly used are detonation nanodiamond powders that have been used to construct cavity electrodes, [5][6][7] sintered into pellet electrodes 8 or dropcoated from solution onto electrodes. 2,3,9 Detonation nanodiamond is synthesised by detonation of carbon-based explosives in the absence of oxygen, resulting in a carbonaceous soot from which the nanodiamond powder can be extracted and puried.…”

Modification of an electrode with an immobilised layer of nanodiamond is found to significantly enhance the recorded currents for reversible oxidation of ferrocene methanol (FcMeOH). Current enhancement is related to nanodiamond diameter, with enhancement increasing in the order 1000 nm < 250 nm < 100 nm < 10 nm < 5 nm. We attribute the current enhancement to two catalytic processes: i) electron transfer between the solution redox species and redox-active groups on the nanodiamond surface; ii) electron transfer mediated by FcMeOH(+) adsorbed onto the nanodiamond surface. The first process is pH dependent as it depends on nanodiamond surface functionalities for which electron transfer is coupled to proton transfer. The adsorption-mediated process is observed most readily at slow scan rates and is due to self-exchange between adsorbed FcMeOH(+) and FcMeOH in solution. FcMeOH(+) has a strong electrostatic affinity for the nanodiamond surface, as confirmed by in situ infrared (IR) experiments.

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.
