abstract = "The great importance of Boron Doped Diamond Titanium (BDD-Ti)
electrodes is correlated to demanding application such as
wastewater treatment, electroanalysis and electrosythesis [1]. In
this work, we report the obtention of a net-like BDD-Ti electrode
candidate to electrochemical applications. Expanded titanium in a
net configuration was utilized as substrate for the diamond film
growth. The substrate was previously purified in oxalic acid; sand
blasted, and than ultrasonically treated with diamond powder for
provides enhanced diamond nucleation. BDD diamond films were grown
by Hot Filament Chemical Vapor Deposition (HFCVD) technique at 870
K from a H2-CH4 (1%-90%) mixture, with a boron doping level of
5000 ppm and a total pressure of 6.6 kPa. Top view images of
diamond films were obtained by Scanning Electron Microscopy (SEM).
Film quality and diamond content were analyzed by Raman
Spectroscopy recorded by a Renishaw microscope system 2000 in
backscattering configuration. Electrochemical investigation for
characterizing the electrode was carried out by Cyclic Voltammetry
in 0.1 M KCl electrolyte. A simple threeelectrode (work electrode,
counter electrode and reference electrode) inside of a
singlecompartment electrochemical cell was used in this study. The
electrodes were not submitted to surface pretreatment before
electrochemical measurements. Ag/AgCl and platinum were used as
reference and counter electrodes, respectively. The Net BDD-Ti
electrode showed a suitable electrical conductivity for using as
an electrode material in electrochemical applications.",
