Hydrothermal Synthesis and Photocatalytic Activities of SrTiO3‐Coated Fe2O3 and BiFeO3

Synthesis of SrTiO3-coated BiFeO3 (see Figure) and Fe2O3 metal-oxide particles has been performed using low-temperature hydrothermal techniques. The coated materials suggest a promising new and general strategy for the sensitization of UV-active metal oxide photocatalysts to visible light.
