Abstract: Photo electrochemical electrodes of lithium based mixed molybdate of Sr (II) was prepared from solution phase. Its chemical composition was determined by estimating the metal contents in it. The material was characterized by X-ray diffraction (XRD), electrical conductivity and diffuses reflectance spectroscopy. Lithium based mixed molybdate of Sr (II) seems to be a good choice as photoanode in a PEC cell because of its 2.36 eV band gap. The flat-band potential is located at - 0.16 V vs saturated calomel electrode. The power conversion efficiency was found to be 0.19 %.
