Preparation and properties of titanium trisulfide nanoparticles

Resumo

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.
