“…Different kinds of diamond nanoparticles (e.g., surface graphitized diamond nanoparticles with a diamond core covered by a graphitic carbon shell, bucky diamond nanoparticles with a nanoscale diamond core surrounded by a fullerene shell, and graphene coated diamond nanoparticles) have been used as the support to load catalysts (e.g., Pt [87][88][89][90][91][92][93], Ni [94,95], Ti [96], Pd [97], Pt/Ni [98], Pt/Ru [99][100][101][102], Sn/Pb [103], Pt/Eu [91,99], and metal oxides [104][105][106]). The mostly investigated electrocatalytic reactions include electrocatalytic oxidation of methanol/formic acid/CO as well as oxygen reduction reaction.…”

“…The mostly investigated electrocatalytic reactions include electrocatalytic oxidation of methanol/formic acid/CO as well as oxygen reduction reaction. To load these catalysts on diamond nanoparticles, numerous approaches have been developed, including electrodeposition [88,92], chemical reduction [93], and microwaveassisted polyol synthesis [91,99]. For example, electrodeposition of Pt nanoparticles on un-doped diamond nanoparticles (5-100 nm in diameter) were conducted in 1.1 mM chloroplatinic acid solution.…”

“…The Pt/Ru nanoparticles were small and uniform with the size of 2-4 nm, and highly dispersed on the surface of diamond nanoparticles [102]. A simple ultrasonic treatment in the presence of diamond powders prior to electrodeposition improved spatial distribution and a higher Pt dispersion over the electrode [99][100][101][102]. A two-step method was reported to modify diamond nanoparticles with Pt and TiO 2 nanoparticles, namely first by a microwave hydrolysis step, and then electrodeposition of Pt nanoparticles [104][105][106].…”

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.

“…However, as indicated by the authors, the fact that Pt-Ru exhibited lower potentials than Pt may be expected in the basis of previous studies [34]; nevertheless, more investigation is necessary to completely understand the composition and particle size effects. The electrodeposition of Pt-Ru electrocatalytic particles was recently studied by comparing simultaneous and sequential deposition on BDD supports using a potentiostatic method [35]. Smooth cluster morphologies were observed for simultaneous deposition and a dendritic structure was observed for sequential deposition from SEM studies ( Fig.…”

The aim of this chapter was to summarize the techniques used for surface modification of BDD materials, improving their catalytic efficiency as supported catalysts for PEM fuel cells (methanol and ethanol oxidation) as well as the studies concerning to the production of electrochemical capacitors using BDD materials. Also, the recent advances on the use of modified BDD materials for fuel cells will be discussed. IntroductionPetroleum is considered the main source of energy, but it has also caused considerable amount of damages such as atmospheric pollution and global warming. Nevertheless, the copious uses of petroleum as well as the demand of petrol in the near future have motivated scientists around the world to develop new clean and renewable energy sources. In this frame, the development of fuel technology has received great attention because this technology consists in directly converting

Catalytic layers of polymer electrolyte membrane fuel cell (PEMFC) electrodes are usually composed of platinum nanoparticles dispersed on an electron conductive carbon support, which can undergo several degradation processes like dissolution of Pt and carbon corrosion under PEMFC working conditions. In this context, the major advantage of conductive boron-doped diamond (BDD) surfaces is their mechanical and chemical stability. BDD is also considered as a good substrate for studying the intrinsic properties of deposited catalysts, avoiding some problems encountered with other substrates, that is, surface corrosion, oxide formation, or electronic interactions with the deposit. Thus, the first part of this review summarized the surface modification of BDD materials, with emphasis in different techniques, to improve the catalytic efficiency of supported catalysts for PEMFCs. In addition, it is known that graphite carbon or lithium metal alloys used in advanced lithium-ion high-energy batteries suffer morphological changes during the charge-discharge cycling, which in turn results in a very poor cycle life. Thus, the use of diamond materials in these applications was also reviewed, since they have very stable surfaces and exhibits excellent electrochemical properties when compared with other carbon forms like glassy carbon and highly oriented pyrolytic graphite.
