A uniform heterojunction photocatalyst of FeTiO 3/TiO 2 composite (FTC) was synthesized by a facile hydrothermal method. The structure, morphology, and spectral properties of FTC were characterized by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and UV-Vis diffuse reflectance spectroscopy. The FeTiO 3 content can be easily tuned by tailoring the precursor amount. The FTC exhibits remarkable photocatalytic activity on CO 2 reduction to CH 3OH under both visible and UV-Vis light irradiation, presumably due to its unique band structures and the efficient charge transfer between two semiconductors as well as the low band gap of FeTiO 3.
