FeVO4 was synthesised using a low temperature, aqueous precipitation reaction. The material prepared directly from this synthesis was found to be predominantly amorphous and required a thermal treatment. The resultant material was characterised using XRD, FT-IR, Raman spectroscopy and magnetic susceptibility measurements. Materials annealed above 600Â Â°C were found to consist mainly of FeVO4, although traces of hematite were found following annealing at higher temperatures. Diffuse-reflectance UV spectroscopy and subsequent Tauc plots revealed a band gap of ca. 2.00Â eV corresponding to an indirect transition. Photocurrent-voltage characteristics recorded under simulated solar illumination indicate that photocurrents are sensitive to annealing temperature and the number of layers deposited on an electrode surface.
