%X Due to its importance in hydrogen production during the photolysis process of aqueous suspensions process, mixed TiO<sub>2</sub>/V<sub>2</sub>O<sub>5</sub> metal-oxide semiconductors were prepared and subjected to crystal structure investigation using X-ray technique. The photoelectrochemical behavior of these TiO<sub>2</sub>/V<sub>2</sub>O<sub>5</sub> was investigated by photolysis of aqueous suspensions of these oxides containing [Fe(CN)<sub>6</sub>]<sup>4-</sup>. X-ray diffraction analysis indicated that the TiO<sub>2</sub> crystallites grow in the (1 0 1) direction, while The V<sub>2</sub>O<sub>5</sub> crystallites seem to be growing in the (4 2 0) direction, with increasing concentration of V<sub>2</sub>O<sub>5</sub>. Photolysis studies show that photochemical activities that maintained the [Fe(CN)<sub>6</sub>]<sup>4/</sup>[Fe(CN)<sub>6</sub>]<sup>3-</sup> redox reversibility increased by increasing V<sub>2</sub>O<sub>5</sub> up to 50% and then decreased at greater percentages. Aqueous nano systems used in these studies retained their stability as indicated by the reproducibility of their photo-catalytic activities.
