ABSTRACT
Bulk titanium nitride (TiN) was synthesized by nitridation of TiO2 rutile substrates. TiN pellets were successfully achieved at 1100⯰C in ammonia stream; these materials were characterized by the evaluation of their microstructure, surface, chemical composition and electrical and electrochemical properties, concluding that the synthesis promotes the creation of a TiNxOy surface, which shows high metallic conductivity (close to 102â¯S/cm) and a microstructure with micro- and nano-features. Electrochemical studies reveal high storage capacities which are delivered through an injection mechanism that involves the double charge layer and EIS show a high capacitive contribution to the mechanism. Neuron cell cultures assessed the biocompatibility of the sample prepared and put forward this material as a promising candidate for implantable stimulation electrode in neuroscience.
