Abstract: We present the optical absorption spectrum of BiTaO4 using the photo acoustic spectroscopy (PAS) technique and first principles approach. Band gap have been estimated 2.65 and 2.45 eV using PAS method and DFT calculations, respectively. Position of reduction and oxidation level with respect to vacuum level are identified, which shows that BiTaO4 can be used as photocatalyst for hydrogen production. Electronic structure is explained by plotting total density of states (TDOS) (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
