The results of the production and characterization of SrCO 3 –SrTiO 3 nanocomposites as a promising candidate for efficient photocatalysts are reported. The production is based on a novelty route employing the solvothermal method with strontium chloride and titanium (IV) butoxide as the precursor solutions. The effect on the properties of the nanocomposites due to changes in the content of SrCO 3 and SrTiO 3 is reported. The as-prepared materials were tested in the photodegradation of methylene blue dye in aqueous solutions under the solar light. The reported route allows the production of SrCO 3 –SrTiO 3 nanocomposites with particle sizes ranging between 18 and 29 nm. The SrCO 3 –SrTiO 3 nanocomposites obtained with 19 % of SrCO 3 phase and 81 % of SrTiO 3 (M10) can achieve 94 and 97 % of dye photodegradation after 30 and 120 min, respectively.
