In this study, titanium nitride (TiN) phase was deposited on the surface and into porous structure of three-dimensional graphene (3DG) by chemical method. This method consists of immersing of 3DG into a solution containing Ti ions and annealing under ammonia atmosphere. In this paper, effect of annealing temperature on type of synthesized phases, their morphology, and stoichiometry was investigated. For this purpose, the samples were annealed at three different temperatures of 750, 800, and 850 °C and analyzed by XRD, SEM and XPS. The results showed that increasing of annealing temperature results in increasing of lattice parameter and crystallite size, while decreasing of oxygen content inside TiN structure. Annealing at 850 °C was resulted to the most stoichiometric composition with titanium/ nitrogen atomic ratio of 1.09.
