Evolution of large area TiS₂-TiO₂ heterostructures and S-doped TiO₂ nano-sheets on titanium foils.

ABSTRACT: We report a novel and facile method to synthesize sulfur-doped titanium oxide sheets and realize TiS₂-TiO₂ heterostructures by means of a sequential sulfurization and oxidation step in a dual-zone chemical vapor deposition furnace. The inclusion of chlorine and argon gases during the growth of such titanium-based compounds plays a critical role in the formation of desired geometries and crystalline structures. These heterostructures possess nano-whisker and nanosheet configurations, controlled by adjusting the growth parameters such as temperature, carrier gas and the sequencing between different steps of the growth. The evolution of these complex heterostructures has been investigated using Raman spectroscopy and EDS characterization. The presence of chlorine gas dur
