<jats:title>Abstract</jats:title><jats:p>A novel In<jats:sup>3+</jats:sup>‐doped TiO<jats:sub>2</jats:sub> and TiO<jats:sub>2</jats:sub>/In<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> nanocomposites for photocatalytic degradation of environmental pollutants and stoichiometric degradation of warfare agents were prepared by a homogeneous hydrolysis with urea and thioacetamide, respectively. The prepared samples series TiInTAA were annealed at 600°C. The prepared samples were characterized by X‐ray powder diffraction, IR spectroscopy, Raman spectroscopy, specific surface area (BET) and porosity determination. The method of UV–Vis diffuse reflectance spectroscopy was employed to estimate band‐gap energies. The photocatalytic activity (PCA) was tested by degradation of Orange dye, whereas stoichiometric activity was studied by degradation of sulfur mustard. Incorporation of In<jats:sup>3+</jats:sup> into titania lattice increases PCA of TiO<jats:sub>2</jats:sub> in the visible light and increases stoichiometric decomposition of sulfur mustard against nondoped TiO<jats:sub>2</jats:sub> as well. PCA of TiO<jats:sub>2</jats:sub>/In<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> composite depends on the optimal ratio of TiO<jats:sub>2</jats:sub>:In<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> in composite, while the activity for stoichiometric decomposition of sulfur mustards depends on the content of In<jats:sub>2</jats:sub>S<jats:sub>3</jats:sub> in nanocomposite.</jats:p>
