“…Thus, all diamond CVD techniques are based on gas-phase non-equilibrium, using a high super saturation of atomic hydrogen with various hydrocarbon radicals. This plasma-assisted procedure uses hot filaments 4,7,20 or microwave radiation 21 to activate a gas phase at 2200-2800 C. The latter is more convenient for the deposition of doped diamond on small surfaces whereas the former with multiple filaments is intended for larger substrates. In both cases, the gas phase held at $10-50 mbar consists of a carbon source and hydrogen as the carrier gas, e.g.…”

“…Regardless of the type of substrate used, the surface must be polished with diamond powder or ultrasonicated in a suspension of diamond nanoparticles. 7 Coating with diamond-like carbon on the substrate is another possibility. These resulting diamond crystallites on the substrate's surface are the nucleation sites for the growth of the thin diamond film during the subsequent CVD process.…”

In recent years, conductive diamond electrodes for electrochemical applications have been a major focus of research and development. The impetus behind such endeavors could be attributed to their wide potential window, low background current, chemical inertness, and mechanical durability. Several analytes can be oxidized by conducting diamond compared to other carbon-based materials before the breakdown of water in aqueous electrolytes. This is important for detecting and/or identifying species in solution since oxygen and hydrogen evolution do not interfere with the analysis. Thus, conductive diamond electrodes take electrochemical detection into new areas and extend their usefulness to analytes which are not feasible with conventional electrode materials. Different types of diamond electrodes, polycrystalline, microcrystalline, nanocrystalline and ultrananocrystalline, have been synthesized and characterized. Of particular interest is the synthesis of boron-doped diamond (BDD) films by chemical vapor deposition on various substrates. In the tetrahedral diamond lattice, each carbon atom is covalently bonded to its neighbors forming an extremely robust crystalline structure. Some carbon atoms in the lattice are substituted with boron to provide electrical conductivity. Modification strategies of doped diamond electrodes with metallic nanoparticles and/or electropolymerized films are of importance to impart novel characteristics or to improve the performance of diamond electrodes. Biofunctionalization of diamond films is also feasible to foster several useful bioanalytical applications. A plethora of opportunities for nanoscale analytical devices based on conducting diamond is anticipated in the very near future

Diamond thin films are well known for their unsurpassed physical and chemical properties. In the recent past, research interests in the synthesis of conductive diamond thin films, especially the boron-doped diamond (BDD) thin films, have risen up to cater to the requirements of electronic, biosensoric, and electrochemical applications. BDD thin films are obtained by substituting some of the sp 3 hybridized carbon atoms in the diamond lattice with boron atoms. Depending on diamond thin film synthesis conditions, boron doping routes, and further processing steps (if any), different types of BDD diamond thin films with application-specific properties can be obtained. This paper will review several important advances in the synthesis of boron-doped diamond thin films, especially those synthesized via gas phase manipulation.

“…Based on the literature, several groups have reported different experimental results using diamond electrode for purification/disinfection water, under different conditions [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] . However, the most relevant publications were taken into consideration here for illustrating the advances of this kind of electrochemical application.…”
