High surface area BiFeO 3 thin films were deposited on ITO substrates by templates method and chemical solution deposition. The resulting phase composition and microstructures were characterized using X‐ray diffraction, scanning electron microscopy and Raman spectroscopy. We further demonstrated the useful photocatalytic activity of these films as determined by degradation of Congo red under visible‐light irradiation ( λ > 400 nm). Our results showed that the surface area have a great effect on the photocatalytic performances of the BiFeO 3 thin films.
