| Research Abstract |
Z scheme water splitting was examined by the combination of H_2 and O_2 evolving photocatalysts of Ru/SrTiO_3 : Rh and BiVO_4, respectively, in the presence of a water-soluble copper(II) complex as an electron mediator at neutral pH under visible light irradiation, to afford H_2 and O_2 with relatively high efficiency. To enhance the photocatalytic property, nanowire-shaped semiconductor photocatalyst was also developed by the reaction of the niobium complex and trioctylamine, because the nanowire generally possesses high surface area, leading to the enhanced adsorption of the mediator on the photocatalyst. Sodium niobate nanowire was employed as a photocatalyst for overall water splitting under UV light irrafiation to show photocatalytic activity for the first time.
