Stable colloidal dispersions with a 2 mM TiS3 concentration (300 mg/l) are obtained by ultrasonic treatment of TiS3 in acetonitrile and isopropyl alcohol and characterized by physicochemical methods. The electrical double layers for the particles in dispersions are estimated from the measured ζ-potentials, and the energies of interparticle interactions are calculated based on the Derjaguin–Landau–Verwey–Overbeek theory. The structural and spectroscopic identity of the particles and crystalline TiS3 is demonstrated for the solid phases obtained from the dispersions.

TiS//3 single crystals have been grown by chemical vapor transport. They were characterized by X-ray diffraction and measurement of their electronic transport properties. A photoelectrochemical study shows both anodic and cathodic dark currents and anodic photocurrents. Flat-band potentials and anodic corrosion potentials in acidic and basic solutions and in the presence of an I//3** minus /I** minus redox couple have been determined from the onset of photocurrent and from the Schottky-Mott plot of capacitance. The flat-band potential exhibits a pH dependence but is almost independent of the presence of I** minus in solution. The stability of this material in a 1N H//2SO//4 plus 1N I//3** minus /I** minus solution has been observed for a period of fourteen days with a photocurrent of approximately 1mA/cm**2. A particular photocorrosion mechanism is reported. The reaction starts at the edges of the layer and proceeds toward the interior. These mechanisms are discussed in relation to the existence of two types of S atoms in the structure: sulfur dimers and S**2** minus ions.
Novel low temperature synthesis of titanium sulfide
Bensalem,Schleich
, p. 857 - 868 (1988)
Amorphous titanium sulfides were synthesized by the direct reaction between dry organic sulfurizing agents and TiCl4. A detailed discussion is given about the reactivity of TiCl4 with each sulfurizing agent. All of the usual crystalline titanium sulfide phases (Ti3S4, TiS2, TiS3) were also synthesized by simply heating the obtained amorphous powder or by heating this powder in the presence of sulfur. These reactions occurred very rapidly and allowed for the simple synthesis of all the crystalline phases.
An X-ray spectrscopy study of the electronic structure of TiS3

X-ray photoemission and absorption spectra of TiS3 are studied. The temperature dependence of the magnetic susceptibility is measured and the electron density of states is calculated. Titanium ions in different oxidation states are found to coe

STRUCTURAL, OPTICAL, AND ELECTRONIC PROPERTIES OF Li//3MS//3 COMPOUNDS (M**I**I**I equals Ti,Zr,Hf).

, p. 257 - 271 (1988)
The Li//3MS//3 powder samples (M**I**I**I equals Ti,Zr,Hf), chemically prepared under mild conditions, have been studied by X-ray diffraction, infrared and Raman vibrational spectroscopies, UV-visible absorption, and electron paramagnetic resonance (EPR) technics. From X-ray data we confirm the topochemical mechanism of three lithium insertions into the 2D-MS//3 host lattices already proposed by R. R. Chianelli and M. B. Dines. From infrared and Raman results new structural information is obtained: on the one hand, the cleavage of (S//2)**2** minus pairs induces a new arrangement of the basic structure and on the other hand, Li-S interactions are by far predominant within strongly distorted two LiS//4 and one LiS// 6 groups; moreover M-S interactions are markedly weakened.
Modification of electronic structure by charge transfer and molecular motion in titanium disulfide-ethylenediamine intercalation compound
Ogata,Fujimori,Miyajima,Kobashi,Chiba,Taylor,Endo
, p. 701 - 710 (1997)
An attempt at modifying the electronic conduction mechanism by guest-host charge transfer and thermally excited molecular motion reported. Ethylenediamine was intercalated into a semiconducting layered material, titanium disulfide, and a significant increase in charge carriers was evidenced by metallic conductivity, Pauli paramagnetism, and conduction electron spin resonance. Rotational motion of the guest molecule was evidenced by the proton spin-lattice relaxation measurement. However, no anomalous behaviors were found on the electronic properties which are attributable to motion-induced modification of the electronic state.

The search for novel photocatalysts that make use of almost the entire solar spectrum remains an ongoing task to achieve high efficiency in energy conversion. While titanium chalcogenides offer a variety of phase compositions with different photophysical properties, their photocatalytic performance in pollutant degradation has not been investigated to date. In contrast to the model photocatalyst titanium dioxide, titanium chalcogenides possess small band gaps which make them eligible to absorb light in the visible range up to the near-infrared region, thus making them interesting candidates for photocatalysis. Herein titanium chalcogenide-based photocatalysts are synthesized by the chemical vapor transport (CVT) method and studied for their photocatalytic activity towards pollutant degradation. A series of titanium chalcogenides TiXn (X = S, n = 1-3; X = Se, n = 2; X = Te, n = 1) have been characterized by a variety of physico-chemical methods. Due to the expected non-stoichiometry of some titanium sulfides, they offer a large number of defect states which make them interesting candidates for photocatalysis. Thus, these titanium-chalcogenides were systematically studied for the photocatalytic degradation of pollutants using methyl orange dye as the test pollutant under simulated sunlight. Particularly TiS and TiS3 show high photocatalytic and thermocatalytic activity, outperforming the activity of titanium dioxide (pure anatase). By controlling the ratios of titanium and chalcogen elements and the specific reaction conditions, a variety of titanium chalcogenides with different compositions and phases showing a high photocatalytic activity can be accessed. Furthermore, it is found that the formation of a titanium dioxide passivation layer during photocatalysis results in a titanium oxide/titanium sulfide heterostructure. This allows further enhancement of the photocatalytic and thermocatalytic activity compared to the bare Ti-chalcogenides.
