“…The specific capacity equals 2.6 mF cm −2 for the CF produced at 1300 K. Similar works were performed also in the case when the gas mixture was enriched with the boron source, resulting in BDD coverage over the carbon fiber with a doping level of 1.5×10 21 cm −3 . The electrochemical performance revealed the strengthened capacitive behavior owing to the increased surface area.…”

Owing to the popularity of carbon‐based supercapacitors, diamond has been examined as a potential candidate for such devices with unique advantages such as a wide electrochemical potential window and stable capacitive behavior in both aqueous and non‐aqueous electrolytes. Moreover, its chemical stability in harsh environments at extreme applied potentials and currents provides unique opportunities for designing new supercapacitors. Owing to the intrinsic low surface area of diamond, it is necessary to increase the electrochemically active surface area or to produce diamond‐based composites, thereby ensuring capacitance improvement for the practical applications. According to previous literature reports, nano‐engineered diamond structures can achieve a specific capacitance values as high as 10 mF cm−2 with a specific energy of 10–100 Wh kg−1 in aqueous electrolyte. The present manuscript reviews the recent advances in this topic of research by highlighting the potentials and challenges of diamond‐based supercapacitors. Special attention is paid to the fabrication methods and electrochemical performance of particular material combinations in view of further application for supercapacitor construction.

“…Later, these authors carried out the morphologic and electrochemical characterization of carbon fibers (CF) and their hybrid material formed by BDD films grown on CF [58]. Figure 7.19 shows the composition of CF surfaces, treated at 1,000 and 2,000°C, associated with their respective SEM micrographs.…”

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
