BaTiO 3 -TiO 2 nanoparticles were fabricated by a wet-chemical method using barium chloride dihydrate (BaCl 2 ·2H 2 O), titanium dioxide (TiO 2 ), and oxalic acid (C 2 H 2 O 4 ) as precursors. BaTiO 3 -TiO 2 -graphene nanocomposites were obtained by heating the BaTiO 3 -TiO 2 nanoparticles with graphene in an electric furnace at 700 °C for 2 h. X-ray diffraction analysis revealed that the resulting products were BaTiO 3 -TiO 2 -graphene nanocomposites. Scanning electron microscopy revealed the morphologyof the nanocomposites. UV-vis spectrophotometry was used to analyze the photocatalytic degradation of several organic dyes using the BaTiO 3 -TiO 2 -graphene nanocomposites as a photocatalyst under ultraviolet irradiation at 254 nm.
