Homogeneous hydrolysis of titanium oxo-sulfate and iron(III) sulfate has been used to prepare anatase TiO 2 and ferrihydrite with high specific surface area. Resulting samples were characterised by specific surface area (Brunauer-Emmett-Teller method) and porosity (Barrett-Joyner-Halenda method) measurements, X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The samples of anatase TiO 2 and ferrihydrite were evaluated for their ability to degrade chemical warfare agents (sulfur mustard gas, soman and agent VX) to non-toxic products. The largest percentage of mustard gas converted into non-toxic products after the completion of the reaction was 99%.
